is my loop badly set up?

With this simple program I am trying to make -- I need to use a while loop to take input from the user until they don't want to input anymore and then calculate the average of what they are entering(they are entering numbers).

So far - I'm having trouble getting my loop to work properly... If I'm not mistaken I think my while loop is crappily set up, but I'm not sure how to improve it... So what I'm asking you all - is if there is a better way to set up this loop - or if my seemingly easy way out works well enough!

The code works fine - I'm just thinking that my loop is badly set up, is it?

Code:

#include <cstdlib>
#include <iostream>
#include <iomanip>

using namespace std;

int main()
{
    
   float number = 0;
   int numbers = 0;
   float sum = 0;
   float average = 0;
   char answer = 'y';
   
    while(answer == 'y'){
                
                 cout <<"Enter a number: ";
                 cin >> number;
                 numbers++;
                 
                 sum += number;
                 
                 cout <<" Do you want to input another number? (y/n) ";
                 cin >> answer;
                 answer = tolower(answer);
                 
                 
                 }
                 
    
    average = sum / numbers;
    cout <<"\nThe average of all the numbers you entered is: ";
    cout << setprecision(3) << average;
    cout << endl;
                 
                 
    
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

No not really. The indentation might be a little exaggerated though and it doesn't care if a user enters something different than 'y' or 'n'.

And the system call is bad

Nevermind the system call - as I won't be sharing this with anyone buy myself.
