Hi

I have been trying to fix the error for the last half an hour. For heaven's sake, could you please help me? Please do. Thanks a lot.

When I run the code the screen just starts scrolling continuously.

#include <iostream>
#include <cstdlib>

using namespace std;

int main()

{
    float m, a, f;
    char v;

    do
    {
        cout << "enter mass: ";
        cin >> m;

        cout << "enter acceleration: ";
        cin >> a;

        f = m*a;

        cout << "force is: " << f << endl;

        cout << "do you want another calculation? press y/n";
        cin >> v;
    }

    while (v != 'n');

    system("pause");
}

Yes, it will do that if you type in anything other than a single letter to your "again?" prompt.

So sorry, Salem. I was stupid I was entering letters where I should have used numbers. Otherwise the code is fine. Thanks for helping with some many queries. You are really nice.
