Error in program using vectors, list, and user defined class

Hi guys,
I'm getting an error i cannot figure. Here is my code

I get this error at compilation

Any help would be appreciated,

Never mind guys, i figured it out...AFTER a couple of hrs!!

Hhhmmm, did you forget the std:: before vector? I have been burned too many times with that error.

One way around that problem is to add the following after your STL headers. Now you can write "vector" instead of "std::vecto r".

#include <vector>
#include <list>
using namespace std;
