    Re: Fun C++ Problem

    -20 + 20 = 0.

    Take a look at the for loop, and the terminating condition. Since on the 20th iteration:
    i + n =
    -20 + 20 =
    0 =
    false

    The loop terminates.

    Negating a negative gives you a positive.


    int i, n = 20;
    for (i=0;-i<n; i--)
    {
    cout << "x" << endl;
    }

    A hint to the third solution, if it's the one I think some here are having a problem with, is "do the math".
