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.

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.

Information security governance aims at providing direction to the executive management to implement a security program that ensures sufficient security to protect the information assets of an organisation. It consists of;

- Alignment of information security strategies and objectives with business strategies and objectives.

- Ensuring that risks are properly addressed.

- Promoting a positive security environment.

- Ensuring compliance with internal and external security requirements.

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.

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.

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

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

Got both answers correct in the class thanks to the guy above me!

Explanation:

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.

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.

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.

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.

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!!
