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:

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:
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.
