    Can you post more code? That printf is simply like:

    cout << i;

    However more is going on than we can see.

    cin >> numb;

    The printf() is like cout << i;

    Generate a random number which initializes some loop. The loop then calls function which returns a random x/y coordinate. This loop executes a random number of times.

    The end result, a random number of ships placed at random points on the board. Use mod to help narrow down the random numbers to something acceptable.

    In the future, make sure to indent your code. We don't want to wade through ugly, unintended code to help people. You'll get more responses that way and it will help you find own mistakes, as well.
