include using namespace std int main int num cout

      }

}

Type in the above program, compile and run.

Add the steps to total the numbers entered.

Add the steps to count how many numbers were entered.

Add the steps to compute the average.

Test with values you know the answer to.

Be sure and test for no values entered and make the appropriate correction to you code.

Solution

#include <iostream>

using namespace std;

int main()

{

int num,sum=0,count=0;

float avg=0;

      cout << endl << \"Enter numbers, 999 to quit\" << endl; //1 - START

      cin >> num;   //1 - START

      while (num != 999)        //2 - TEST

       {

          cout << \"Number entered is: \" << num << endl; //3 - ACTION

      sum+=num;

          cout << \"Enter numbers, 999 to quit\" << endl; //4 - RESTART

          cin >> num;   //4 - RESTART

      count++;

       }

      cout<<\"Total sum of entered number is \"<<sum<<endl;

      cout<<\"Total number of elements entered is \" <<count <<endl;

      cout<<\"Average = \"<<(float)sum/count<<endl;

       return 0;
