Agreed about the using namespace std, but I guess code style can be fixed after you have something running and understand it.

This page explains different uses of function names:
http://www.cprogramming.com/declare_vs_define.html

It also has a really simplified example, but it's similar to what you have with Display() showing up three times. Just copying the code here for convenience:
Code:
int func();

int main()
{
    int x = func();
}

int func()
{
    return 2;
}
See the section with this code, it'll explain the reason for func() showing up 3x.
