Before start the program, see the recursion function of 'cheers' in Self-Test Exercise1. Now need to convert from recursive function to iterative function.

Iterative function of 'cheers ':

//Iterative version of the function 'cheers'
//Function "cheers" accept an integer parameter value of n
//and check the while loop condition to print result on screen
void cheers(int n)
{
    while (n > 1)
    {
        cout << "Hip ";
       n--;
    }
    cout << "Hurray\n";
}

Complete program by using above iterative function:

//Header section
#include <iostream>
using namespace std;
//Function prototype
void cheers(int n);

//main program
int main( )

{
    //Call the method
    cheers(3);
    return 0;
}
//Iterative version of the function 'cheers'
//Function "cheers" accept an integer parameter value of n
//and check the while loop condition to print result on screen
void cheers(int n)
{
    while (n > 1)
    {
        cout << "Hip ";
       n--;
    }
    cout << "Hurray\n";
}

Output of the program:
