Question

Please design, write the code and create the requisite submission files in C++ for the following problem:

A menu-driven program that offers the user 5 options as follows:

Menu:

1. Display array

2. Add up all elements in the array and display that number.

3. Add 1 to each element in the array.

4. Swap the values in row one with the values in row three.

5. Exit

In main(), declare and initialize a 2-dimensional array that contains 5 x 5 elements. Initialize the elements to:

2,8,6,16,10

-1, -2, -3, -4, -5

9,6,9,20,27

49, 63, 89, 12, 17

-900, -800, 800, 600, 200

Display the menu and then execute the user's choice. Keep displaying the menu (and executing the user's choice) until the user chooses Option 5. (See pseudocode in this lesson for design help.)

Execute the chosen menu option by passing the array to a specific function which will do the work (in other words, there will be 4 array processing functions and one exit function).

No global variables, although global constants are fine. Remember, you MUST pass the array to the functions and not do the work in main().

Pseudocode for driving a menu (see how the default part of the switch statement catches the bad menu input?)

choice = 0;

while (choice != 3) //assume 3 is the exit out

choice = functionDisplayMenu()

switch on choice

case 1:

functionOption1(myArray);

break;

case 2:

functionOption2(myArray);

break;

case 3:

functionExitCode()

default:

displayError("wrong menu choice")

end switch

end while

Dear Student,

Here is the complete C++ program which fullfill the requirement of the given question.

Plese note that the below program is tested on ubuntu 14.04 sytem and compiled under g++ compiler.

Program:

----------------------------------------------------------------------------------------------------------------------------------

//Inclusion of header files

#include<iostream>

#include<stdlib.h>

#include<string.h>

#include<iomanip>

// Name Space Declaration

using namespace std;

//Starting of Main Function

int main()

{

//Data Type Declaration

char option;

int i, j;

int sum =0;

int temp[5][5];

// Array Initialization

int array[5][5] = {{2,8,6,16,10},{-1,-2,-3,-4,-5},{9,6,9,20,27},{49,63,89,12,17},{-900,-800,800,600,200}};

// Display Menu on the Screen

do

{

cout <<"\n1.Display array"<<endl;

cout <<"2.Add up all elements in the array and display that number"<<endl;

cout <<"3.Add 1 to each element in the array"<<endl;

cout <<"4.Swap the values in row on with the values in row three"<<endl;

cout <<"5.Exit"<<endl;

cout << "\nPlease select the option to perform from the above given menu: ";

cin >>option;

//Switching to case as choice selected by the user

switch(option)

{

case '1':

        for(i=0;i<5;i++)

        {

        for(j=0;j<5;j++)

        {

        cout<<array[i][j]<<"\t";

        }

        cout<<endl;

        }

        break;

case '2':

        for(i=0;i<5;i++)

        {

        for(j=0;j<5;j++)

        {

        sum = sum + array[i][j];

        }

        }

        cout<<"\nSum of all the array element is: "<<sum<<endl;

        break;

case '3':

        for(i=0;i<5;i++)

        {

        for(j=0;j<5;j++)

        {

        array[i][j] = array[i][j]+1;

        cout<<array[i][j]<<"\t";

        }

        cout<<endl;

        }

break;

case '4':

       cout<<"After Swaping the elements of array are: ";

       for(i=0;i<5;i++)

        {

        for(j=0;j<5;j++)

        {

        temp[0][j] = array[0][j];

        array[0][j] = array[2][j];

        array[2][j] = temp[0][j];

        cout<<array[i][j]<<"\t";

        }

        cout<<endl;

        }

        break;

case '5':

        cout<<"Exiting from the program. Thank you..!!!"<<endl;

        return 1;

        break;

default:

        cout<<"Wrong Menu Choice"<<endl;

}

}while(option!=5);

return 0;

}

// End of the main function

Here i have attached the output as a screen shot which shows all the operations...

Output:

------------------------------------------------------------------------------------------------------------------------------------

3.Add 1 to each element in the array 4.Swap the values in row on with the values in row three 5. Exit Please select the option to perform from the above given nenu: 4 After Swaping the elements of array are: 10 7 10 21 28 3 50 899 1 9 64 799 7 90 801 17 13 601 18 201 1.Display array 2.Add up all elements in the array and display that number 3.Add 1 to each element in the array 4.Swap the values in row on with the values in row three 5.
