Please remember to use code tags, there's a big button which says (Code) in the reply box now, so there's really no excuse for missing it other than a lack of effort.

Now some points about your code, your teacher shouldn't be making you use Turbo C++, it's outdated, and can be replaced by one of many free compilers available online. However as you're using graphics.h, I doubt you're going to bother changing. Unfortunately, this means helping you wont be easy, as there are no good programmers using Turbo C++ anymore.

void main() Don't use void main, it's bad practice, just use int main() and save yourself a few problems.
