Using do while loop to get the average of ten numbers.

[amgs65]

I have an assignment to do in C++. I need to use do while loop to get the average of ten numbers. I'm having a very hard time. Can someone help me out? Thanks in advance!

show us what you have so far.

For now I only know how to use for loop. I need some help converting this to do while loop.

#include <iostream>
using namespace std;

int main()
{
  int num;
  float input, sum=0, avg;

  cout<<"Input the amount of numbers: ";
  cin >> num; 

    for(int i = 1; i <= num; i++){
      cout<<"Enter a number: ";
	  cin >> input;
      sum += input;
    }

  avg = sum / num;
  cout << "The average is = " << avg << endl;

return 0;
}

It's trivial to convert a for loop to a while loop.

The for loop statement already contains:

- initialisation of pre-loop stuff
- the condition that will be checked on every iteration to see if the loop keeps gpoing
- the thing that changes in every iteration of the loop

That's all you need to make a while loop. If you understand the syntax of a for loop, and the syntax of a while loop, then you have everything you need.

(And if you don't understand the syntax of those, you should really be going and learning that, before attempting to write code.)
