Answer:
Following are the program to this question:
val=input("")#defining val variable that inputs value
print('Hello',val,', we welcome you...')#defining print method, that print input value with the message
Output:
Pat
Hello Pat , we welcome you...
Explanation:
In the above given, python code a "val" variable, and the print that is inbuilt method is declared, inside the "val" variable the input method is used, which is used to input the value from the user side.
In the next line, the print method has declared, which is used to print the value with the message.
Different network scenarios require the use of different tools. The tools you may consider should EXCLUDE:_________
Complete Question:
Different network scenarios require the use of different tools. The tools you may consider should EXCLUDE:
a. Port scanner
b. Banner grabbing tools
c. Vulnerability scanner
d. Honeypots
e. Protocol analyzer
f. Viruses
g. Honeynets
Answer:
f. Viruses
Explanation:
Different network scenarios require the use of different tools. The tools you may consider should include:
a. Port scanner: this is a program used by network administrators to scan various application, transport, internet and network ports which may be exploited by hackers or attackers when found vulnerable.
b. Banner grabbing tools: it is used to gather informations of a computer residing on a network and various services running on its open ports using telnet, zmap, netcat and nmap.
c. Vulnerability scanner: used for the detection of vulnerabilities in a network or systems.
d. Honeypots: it is used to detect and redirect or prevent any unauthorized use of information of a network by mimicking the potential target systems.
e. Protocol analyzer: it is used to analyze traffic and packet captures in a network. Software programs such as wireshark, tshark can be used for protocol analysis.
f. Honeynets: is a combination of one or more honeypots used for attracting and trapping potential attackers.
However, a virus is a malicious program that can replicate and cause severe damage to a computer system.
Write the ColorfulBouncingCircle class, where you should write the constructor, setPlayingFieldSize, and tick methods, and override the overlaps method, each according to the above descriptions. You should not have to write any code which draws; instead, a test program will be provided which will animate ColorfulBouncingCircles based on your implementation. For every time tick, the test program will compare every circle against every other circle using the overlaps method
Answer: Circle class representing circle objects which have a radius, center x, and center y. It included overlaps and draw methods. Then, we wrote a Colorfulcircle class which included a Color property and overrode the draw method of Circle. For this assignment, you are asked to create a ColorfulBouncing circle class. Begin with the versions of Circle and ColorfulCircle uploaded to Canvas ColorfulBouncingCircle should extend ColorfulCircle, Unlike the other Circle classes, it will include a velocity for the x and y axes. The constructor for ColorfulBouncingCircle includes these parameters: public colorfulBouncingcircle (double radius, double centerx, double center Color color, double xVelocity, double yvelocity) Note that we are treating x as increasing to the right and y as increasing down, as with Java's graphics coordinates system. This was also seen with Circle's draw method. ColorfulBouncingCircles will bounce around in a playing field which the tester will provide. The Colorful Bouncinesicle class should have a public static method to set the playing field width and height: public static void setPlayingFieldsize (double newwidth, double newHeight) ColorfulBouncingCircle will also include a method which should alter its center and center with each time tick (similar to a metronome's noise guiding a musician to play a song). The circle's x position should be altered according to x velocity and y position according to y velocity. However, before changing the positions, check if the center position would, after moving, be either less than 0 or greater than the playing field dimensions. If so, instead of changing the center position, alter the velocity. If the ball hits the top or bottom, the sign of its vertical velocity should be flipped: if it hits the left or right, its horizontal velocity sign should be flipped. If it hits a corner, both should be. Notice that velocity may be positive or negativel The tick method which will be called by the tester is defined in this way:
public void tick() Finally, we should override the overlaps method to make balls bounce away from each other. You should call the super method to see if your circle overlaps another circle. If so, alter this circle's velocity according to its center relative to the other circle. If this circle" is above or below the "other circle," flip the sign of "this circle's" vertical velocity. If it's to the left or right, flip the horizontal velocity As before, both may be flipped. This is NOT the same as a true elastic collision, but it should be simpler for you to implement. The sign flipping will sometimes cause the balls to "vibrate" when caught between each other. Please review the velocity changing rules carefully; they are easy to get wrong!! To review: Write the ColorfulBouncineCircle class, where you should write the constructor setPlayingfield Size, and tick methods, and override the overlaps method, each according to the above descriptions. You should not have to write any code which draws; instead, a test program will be provided which will animate ColorfulBouncingCircles based on your implementation. For every time tick, the test program will compare every circle against every other circle using the overlaps method. The test program will ask you to press Enter in the console to launch the automated tests which will assign a tentative score based on your implementation. DO NOT ALTER the Circle OR Colorful Circle files!!

4.17 LAB: Data File A comma separated value (.csv) file has been included to be used for this program. Each line contains two values, a name and a number separated by a comma (except the first line, which contains the titles for the value types). The name is that of a writer and the number refers to the number of works the writer has written. Ex. Jane Austen,6. Each line is an entry and each entry number can be updated by identifying the associated name. Once complete, the following program opens data file allWorks.csv and asks if the user wants to update entries or add new entries. All entries are stored in an array while being read in and updated. The program then writes the array to the file, overwriting the original contents. The following TODO sections must be completed. Open allWorks.csv for reading/input. Locate an entry to be updated by name (use the Java String indexOf() method) Add a new entry if the name isn't found in the file (give the entry a new number) Open file allWorks.csv for output Write contents of the array to allWorks.csv (original file is overwritten)
Answer:
import csv
def Csvreader(filename):
with open("filename", "r") as file:
content = file.csv_reader()
list_content = list(content)
file.close
return list_content
Explanation:
This is a python description of the function that reads the csv file and converts it to a list, from the list, each item can accessed with its index and updated directly. Use this to draw the same conclusion for a java program.
In a six-story building, which floor would be the best option for the data center?
Answer:
243
Explanation:
Give a tight bound on the number of times the z = z + 1 statement is executed. i = 2 while ( i > 1 ) { i = floor(i/2) z = z + 1 }
Answer:
zero ( 0) times.
Explanation:
In the code;
i = 2
while ( i > 2){
i = floor( i/2 );
z = z + 1;
}
the variable " i " is assigned the integer " 2 ", then the while statement loops with a condition of a greater " i " value and divides the value by two for every loop.
But in this case, the while statement is not executed as the value of " i " which is 2 is not greater than but equal to two.
Which methods are commonly used by sysadmins to organize issues?
a. Random machine checks
b. Daily checks on each machine
c. Service monitoring alerts
Answer:
c. Service monitoring alerts
Explanation:
Given the fact that system administrators manage so many computer systems, they are equipped with service monitoring alerts that indicate when there is a problem with any of the systems and the extent or magnanimity of the problem. This is necessary so as to attract responses from the right personnel.
Metrics are deployed to gather raw data on the system's use and behavior. Monitoring compiles these data to useful information that can be stored when they meet up to some standards. The alert system sends out signals to the administrators when some acceptable standards are not met. So, the service, monitoring alerts are used by system admins to organize issues.

Create a Python script that takes two parameters to do the following:-
1) List all files names, size, date created in the given folder
2) Parameter1 = Root Folder name
Parameter2= File size >>> to filter file size ( you can do =, > or <) it is up to you, or a range.
The script should check and validate the folder name, and the size
The script should loop until find all files greater than the specified size in all the sub-folders
3) Use catch-exception block (Make sure that the error messages do not reveal any of the application code)
4) Optionally, you can save the list into a file "Results.txt" using the redirection operator or by creating the file in the script.
Answer:
import sys, time

if folder_name == True:
for root, folder, files in walk( folder_name ):
for file in files:
if getsize( join ( root, file ) ) >= file_size:
file_log = [ ]
file_log.append( file )
file_log.append( join ( root, file) )
file_log.append( time.ctime( getctime( file ) ) )
file_counter.append( file_log )
else:
remove ( join ( root, file ) )
Explanation:
The python script above output the filename, size and file creation date of any folder passed to it.
You are training to complete in a local 5K run. You record your time scores in minutes after completing seven practice runs. Write a method to calculate and return the average score based on the data.
Answer:
Following are the program to this question:
#include <iostream>//defining header file
using namespace std;
float Avg(float sum, int n)//defining method Avg that accepts float parameter
{
float average=sum/n;//defining float variable average that holds average value
return average;//return average
}
int main()//defining main method
{
float ar[ ] = {24.1,24.5,24.4,23.8,28.2,29.1,27.4};//defining float array
float sum;//defining float variable sum
int n=7,i;//defining integer variable
for (i = 0; i <n; i++)//defining loop to count total of array
{
sum=sum+ar[i];//add value in sum variable
}
cout<<"The average is: "<<Avg(sum,n);//use print method to call and print method return value
return 0;
}
Output:
The average is: 25.9286
Explanation:
In the above code, the float method "Avg" is declared, that accepts two parameters, that is "sum and n", inside the method, a float variable average is declared that divides and returns its values.
In the main method a float array "ar" is declared that holds values, in the next line, float variable "sum" and integer variable "n, j" is used.
In for loop, the "i" variable is used to add array values in the sum variable and pass into cout to call the "Avg" method and print its return value.
write a pseudocode thats accept and then find out whether the number is divisible by 5
Answer:
input number
calculate modulus of the number and 5
compare outcome to 0
if 0 then output "divisible by 5"
else output "not divisible by 5"
Explanation:
The modulo operator is key here. It returns the remainder after integer division. So 8 mod 5 for example is 3, since 5x1+3 = 8. Only if the outcome is 0, you know the number you divided is a multiple of 5.
In order to use an object in a program, its class must be defined.
True
False
In object-oriented programming, what is initializing?
Concatenating the initial values of an attribute
Modifying the initial values of an attribute
Printing the initial values of an attribute
Setting the initial values of an attribute
Answer:
True
Setting the initial values of an attribute
Explanation:
A class in a program describes the contents of the objects that it belongs to and specifies how they behave. It defines the operations (methods).
Therefore, for an object to be used in a program, its class must be defined, which is TRUE.
Initialization with regards to object-oriented programming is defining or assigning values to a constant or variable. Thus, option D is correct as it is setting the initial values of an attribute
Q1: True
Q2: Setting the initial values of an attribute
Explanation:Got both answers correct in the class thanks to the guy above me!
#include using namespace std;void Swap(int x,int y); //prototypeint main(){ int num1, num2; cout << "Please enter two numbers to swap, the same numbers will quit." << endl; cin >> num1 >> num2; while (num1 != num2) { Swap(num1,num2); cout << "After swap, the numbers are " << num1 << " " << num2 << endl; cout << "Please enter two numbers to swap, "; cout << "the same numbers will quit." << endl; cin >> num1 >> num2; } cout << "Thanks!" << endl; return 0; }//***************************//This subroutine swaps two numbers//*****************************void Swap(int x, int y){ int temp; temp = x; x = y; y = temp;}1. Type in the above program as swap.cpp. Add a comment to include your name and date. Compile and run with different values.2. To find out why this is not working, add the following output statements to the swap function.a. cout << " beginning of swap" << x << " " << y << endl;b. cout << " end of swap" << x << " " << y << endl;Are the variables being swapped inside the swap function?3. Explain why this program is not working correctly.4. Fix the program so the swap will work. Compile and run and be sure the swap works.5. Submit a copy of the final listing and output. Also include a copy of the hierarchy chart for the program.
Answer:
Fix:
void Swap(int &x, int &y){
int temp;
temp = x;
x = y;
y = temp; }
See the explanation
Explanation:
1. swap.cpp
//Name: ABC Date: dd/mm/yyyy
#include
using namespace std;
void Swap(int x,int y); //prototype
int main(){
int num1, num2;
cout << "Please enter two numbers to swap, the same numbers will quit." << endl;
cin >> num1 >> num2;
while (num1 != num2) {
Swap(num1,num2);
cout << "After swap, the numbers are " << num1 << " " << num2 << endl;
cout << "Please enter two numbers to swap, ";
cout << "the same numbers will quit." << endl;
cin >> num1 >> num2; }
cout << "Thanks!" << endl;
return 0; }
//********************//This subroutine swaps two numbers // ********************
void Swap(int x, int y){
int temp;
temp = x;
x = y;
y = temp;}
The output of this program with num1 = 1 and num2 = 2 is:
Please enter two numbers to swap, the same numbers will quit. 1 2 After swap, the numbers are 1 2 Please enter two numbers to swap, the same numbers will quit. 1
1 Thanks!
Notice that the numbers 1 and 2 are not swapped correctly even when the Swap() method is called in the main() function.
The other numbers 1 and 1 are entered in order to quit the program.
2.
In this part first output statement a) is added to the start of Swap() method before swapping the numbers x and y and the output statement b) is added to the last after the set of operations performed to swap x and y.
void Swap(int x, int y){
cout << " beginning of swap " << x << " " << y << endl;
int temp;
temp = x;
x = y;
y = temp;
cout << " end of swap " << x << " " << y << endl; }
Lets say x = 1 and y = 2
The output of these two statements is:
beginning of swap 1 2
end of swap 2 1
This shows that the Swap() function is working correctly and swapping the two numbers x and y.
3.
The reason that the program is not working properly is that x and y are value parameters. They are like local variables and local to the Swap() function. So changes made to them have no effect on the calling functions arguments num1 and num2. That is why the result remains the same when this function is called in the main().
In these three statements of Swap() method:
int temp = x;
x = y;
y = temp;
temp is a local variable which is local to this Swap function
Similarly x=y; and y= temp statements make changes only in the local copy and not in the values of num1 and num2 which are passed to this function in main()
So for the above example where num1 = 1 and num2 = 2, the statement
cout << "After swap, the numbers are " << num1 << " " << num2 << endl;
displays:
After swap, the numbers are 1 2
This means their real values are printed as it is without swapping the values.
4.
The solution is to mark the parameters x and y of the function Swap() as reference parameters in the following way:
void Swap(int &x, int &y)
In this way the memory address of each argument num1 and num2 is passed to the Swap(). The Swap() uses this address to both access and change the values.
So Swap(num1,num2); function call passes the memory address the actual parameters.
For the reference parameter an ampersand (&) is used before the variables x and y of Swap method. Now any changed made to these variables will effect the calling function arguments num1 and num2. So if x and y are swapped then num1 and num2 are also swapped when this function is called in main().
So change the prototype of Swap function as:
void Swap(int &x,int &y);
Change the function definition as:
void Swap(int &x, int &y){
int temp;
temp = x;
x = y;
y = temp; }
Now the program gives the following output:
Please enter two numbers to swap, the same numbers will quit. 1 2 After swap, the numbers are 2 1 Please enter two numbers to swap, the same numbers will quit. 1 1 Thanks!
See now the numbers are correctly swapped. The program and its output is attached.
Use the Web to search for methods to prevent XSS attacks. Write a brief description of more than one method.
Explanation:
Cross site scripting is a security vulnerability. it is a client side code injection attack, the attacker tries to execute a malicious JavaScript in the internet browser of the victim. The users browser executes this script on the users computer. Almost one in three websites are vulnerable to cross site scripting. To prevent cross site scripting, scan your web application or website regularly, your developers should also correct the code to eliminate vulnerabilities.Escaping is the first method one should use to prevent XSS attacks. Escaping means whatever data an application receives should be secure before sending it to user. Validating input is he second method, it means one should ensure that the application renders correct data and prevents malicious data from harming the site, database and users. Blacklisting is used for this. IT disallows several predetermined characters in user input. Sanitizing is the third way to prevent XSS attacks. It is helpful on sites that allow HTML markup to make sure that the data which is received is not doing any harm to users or your database by cleaning the data of harmful markups.ven if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are

"The ______ of an operational system that supports an organization includes policies, requirements, and conditional statements that govern how the system works."
Answer:
Decision logic.
Explanation:
The decision logic of an operational system that supports an organization includes policies, requirements, and conditional statements that govern how the system works.
Generally, the decision logic of an operational system comprises of systems which includes pricing, order processing, customer relationship management (CRM) and inventory control. In order to modify the decision logic of information systems, continuous interactions between information technology (IT) analysts and the clients of these businesses are created.
Additionally, operational decision logic are typically visible, can be measured, managed and can easily be shared across processes within an organization through the use of a business rule management system (BRMS).

A. The function definition must appear before the function is called
Explanation:
Given
The above lines of code
Required
Determine the error in the program
In python, functions has be defined before they are called but in this case (of the given program), the function is called before it was defined and this will definitely result in an error;
Hence, option A answers the question
The correct sequence of the program is as follows:
def evenOdd(n):
if n % 2 == 0:
return "even"
return "odd"
num = int(input("Enter an integer: "))
print("The integer is", evenOdd(num))
Design a class named Person with fields for holding a person’s name, address, and telephone number. Write one or more constructors and the appropriate mutator and accessor methods for the class’s fields. Next, design a class named Customer, which extends the Person class. The Customer class should have a field for a customer number and a boolean field indicating whether the customer wishes to be on a mailing list. Write one or more constructors and the appropriate mutator and accessor methods for the class’s fields. Demonstrate an object of the Customer class in a simple program.
Answer:
Here is the Person class:
class Person { //class name
//below are the private data members/fields of Person class
private String name; //to hold name
private String address; //to hold address
private String phoneNo; // contains telephone number
public Person(String name, String address, String phoneNo){ //constructor of Person class with name, address and phoneNo as parameters
this.name = name;
this.address = address;
this.phoneNo = phoneNo; }
public String getName(){ //accessor method to get/access the name
return this.name; } //returns the name
public String getAddress(){ //accessor method to get/access the address
return this.address; } //returns the address
public String getPhoneNo(){ //accessor method to get/access the phone number
return this.phoneNo; } //returns the telephone number
//mutator methods
public void setName(String nam){ //mutator method to set the name
this.name = nam; }
public void setAddress(String addr){ //mutator method to set the address
this.address = addr; }
public void setPhoneNo(String phNo){ //mutator method to set the telephone number
this.phoneNo = phNo; } }
Here is the Customer class which extends the Person class:
class Customer extends Person{ //Customer class that is sub class of Person class
//below are the private data members/fields of Customer class
private String CustomerNo; //String type field to hold customer number
private boolean MailingList; //boolean field indicating whether the customer wishes to be on a mailing list
public Customer(String name, String address, String phoneNo, String custNum, boolean mail) { //constructor of Customer class that has parameters name, address and phoneNo (of Person class) and parameters custNum and mail ( of Customer class)
super(name, address, phoneNo); // super keyword is used to refer to Person objects and to access the Person class constructor
this.CustomerNo = custNum;
this.MailingList = mail; }
//accessor methods
public String getCustomerNo(){ //accessor method to get/access the customer number
return this.CustomerNo; }
public boolean getMailingList(){ //accessor method to get/access the boolean mailing list to check whether a person wants to be on mailing list
return this.MailingList; }
//mutator methods
public void setCustomerNo(String custNo){ //mutator method to set the customer number
this.CustomerNo = custNo; }
public void setMailingList(boolean mailing){ //mutator method to set the mailing list
this.MailingList = mailing; } }
Explanation:
Here is the demonstration class to demonstrate object of Customer class, calls Person and Customer class methods to display the Customer information such as name, address, phone number, customer number and if customer wants to receive mail.
import java.util.Scanner; //used to take input from user
class Demonstration{ //test class
public static void main(String args[]){ //start of main() function
Scanner input= new Scanner(System.in); //creates object of Scanner class
System.out.print("Enter Customer Name: "); //prompts user to enter name
String fname = input.nextLine();
System.out.print("Enter Customer Address: "); //prompts user to enter address
String address = input.nextLine();
System.out.print("Enter Customer Telephone Number: "); //prompts user to enter telephone number
String phoneNumber = input.nextLine();
System.out.print("Enter Customer Number: "); //prompts user to enter customer number
String customerNum = input.nextLine();
System.out.print("Does Customer wish to be on a mailing list? \nPress 1 for yes, 0 for no: "); //asks user if he wishes to receive mail
String choice = input.nextLine();
boolean mailList = (choice.equals("1")); //if user enters 1 indicating that he wishes to be on mailing list
Customer customer = new Customer(fname, address, phoneNumber, customerNum, mailList); //creates object of Customer class and calls Customer class constructor

Lidia is assigning her first name as the value to a variable. Which is the correct format to use? firstName = "Lidia" First Name = "Lidia" firstName! = "Lidia" firstName = Lidia
Answer:
firstName = "Lidia"
Explanation:
firstName = "Lidia"
Answer:
firstName = "Lidia"
Explanation:
you declare a variable by
variableName = value
her name is of data type string, so it should be enclosed in " "
Multisensory input/output devices, such as data gloves or jumpsuits, are commonly used with _______________ systems.
Answer:
virtual reality
Explanation:
Virtual reality is basically a simulated or virtual environment. This environment is implemented by compute technology for the users that can interact with the virtual 3 dimensional objects instead of just watching them on the screen. With the use of multi-sensory input and output devices the senses of the user are simulated.
Virtual reality devices are the products used for interacting with a virtual environment for the users. Some of the multisensory input/output devices include:
data gloves
jumpsuits
track pads
joysticks
treadmills
multi-speaker audio
visual displays
controller wands
head set
For example a data glove enables the users to interact with virtual objects and feel the object rather than just a movement of hand in the air and it is also used in virtual gaming. Jumpsuits are also used to feel sensations in the virtual reality environment. It stimulates different body parts in response to any action taken by user in a virtual environment.

#We've started a recursive function below called #measure_string that should take in one string parameter, #myStr, and returns its length. However, you may not use #Python's built-in len function. # #Finish our code. We are missing the base case and the #recursive call. # #HINT: Often when we have recursion involving strings, we #want to break down the string to be in its simplest form. #Think about how you could splice a string little by little. #Then think about what your base case might be - what is #the most basic, minimal string you can have in python? # #Hint 2: How can you establish the base case has been #reached without the len() function? #You may not use the built-in 'len()' function.
Answer:
Here is the Python program:
def measure_string(myStr): #function that takes a string as parameter
if myStr == '': #if the string is empty (base case)
return 0 #return 0
else: #if string is not empty
return 1 + measure_string(myStr[0:-1]) #calls function recursively to find the length of the string (recursive case)
#in order to check the working of the above function the following statement is used
print(measure_string("13 characters")) #calls function and passes the string to it and print the output on the screen
Explanation:
The function works as following:
Suppose the string is 13 characters
myStr = "13 characters"
if myStr == '': this is the base case and this does not evaluate to true because myStr is not empty. This is basically the alternate of
if len(myStr) == 0: but we are not supposed to use len function here so we use if myStr == '' instead.
So the program control moves to the else part
return 1 + measure_string(myStr[0:-1]) this statement is a recursive call to the function measure_string.
myStr[0:-1] in the statement is a slice list that starts from the first character of the myStr string (at 0 index) to the last character of the string (-1 index)
This statement can also be written as:
return 1 + measure_string(myStr[1:])
or
return 1 + measure_string(myStr[:-1]) This statement start from 1st character and ends at last character
This statement keeps calling measure_string until the myStr is empty. The method gets each character using a slice and maintains a count by adding 1 each time this statement is returned.The function breaks string into its first character [0:] and all the rest characters [:-1]. and recursively counts the number of character occurrences and add 1. So there are 13 characters in the example string. So the output is:
13
