Chapter 1, Problem 2C

Explanation of Solution

Program code:

//include the required header files

#include<iostream>

//define the main() method

int main()

{

//declare an integer variable

const int size=3;

//declare an integer array

int arr[size],count=0;

//prompt the array elements

std::cout<<"\nEnter the contents of the array below\n";

//iterate a for loop

for(int i=0;i<size;i++)

    //scan for the array values

    std::cin>>arr[i];

//print the statement

std::cout<<"\nNOTE:It would not count pairs like (1,1) or (2,2)";

//print the pairs using for loop

std::cout<<"\nThese are the Pairs\n";

for(int i=0;i<size;i++)

{

    //int temp=arr[i];

    for(int j=0;j<size;j++)

    {

        //if i and j are equal

        if(i==j)

            //print

            std::cout<<"";

        //if i and j are not equal

        else

        {

            //if the condition is true

            if(arr[i]*arr[j]%2==0)

            {

                //print the pairs
