stringstream strStream(str);
while (strStream.good())
{
string substr;
getline(strStream, substr, ';');
vec.push_back(substr);
}
for (size_t i = 0; i < vec.size(); i++)
{
total = total + stod(vec[i]);
}
return total;
}
int main()
{
//method calling and display result
cout<<AddAll("1.245;2.9");
}
This gives output as:

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.

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.
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.
In a six-story building, which floor would be the best option for the data center?
Answer:
243
Explanation:
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
System.out.println("\nCustomer Information: ");
System.out.println("Name: "+customer.getName()); //calls getName method of Person class using customer object to get the name and displays the name
System.out.println("Address: "+customer.getAddress()); //calls getAddress method of Person class using customer object to get the name and prints the address
System.out.println("Telephone Number: "+customer.getPhoneNo()); //calls getPhoneNo method of Person class using customer object to get the telephone number and prints phone number
System.out.println("Customer Number: "+customer.getCustomerNo()); //calls getCustomerNo method of Customer class using customer object to get the customer number and prints the customer number
System.out.println("Mailing List?: "+customer.getMailingList()); }} //calls getMailingList method of Customer class using customer object to get the mailing list and prints true of false on the basis of customers choice to be on mailing list.
"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).

C. 5-10 seconds
#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
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.
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.

Complete Question:
Even if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are;
Group of answer choices
A. policy and procedure development
B. use case activity diagram testing
C. method design and coding
D. data conversion and user training
Answer:
C. method design and coding
Explanation:
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;
1. Planning.
2. Analysis.
3. Design.
4. Development (coding).
5. Deployment.
6. Maintenance.
Among the listed stages, there are two (2) most important stages which cannot be ignored in the creation of a software application are.
Hence, even if you skipped all the requirements analysis steps, the two steps guaranteed to be completed in any software development are method design and coding.
I. Method design: this is the third step of the software development life cycle, it comes immediately after the analysis stage. This is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.
II. Coding (development): this is the fourth step in the software development process and it involves the process of creating a source code which would enable the functionality of the software application.
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
from os import walk, remove
from os.path import exists, join, getsize, getctime
file_counter = [ ]
folder_name, file_size = argv
isExist = exists( folder_name )
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.
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!!

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!

//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.Which organization plays a key role in development of global health informatics?
