executing errors

hey, im doing this C++ program and it consists of 3 files, the .h file, the .cpp file, and the main client program. When i compile the program, i get 0 errors and 0 warnings. But then when i try to execute the program, i get 4 unresolved external errors, and it will not execute. Funny thing is that on Microsoft Visual it only does this. But on UNIX it compiles and runs smoothly. This is due in a couple days and i was hoping someone could find out how to fix that problem. Thanx. To email me, email me at. [email protected]

here is a link to my program, i posted it up so that someone can copy and paste the entire program and then compile and see what's wrong with it. Thanx a lot :-)

the link is my program

there is the link again

Compiled and linked ok for me (MSVC.NET). Make sure your setting up the files properly (that your implementation is being compiled).

You may want to be consistent in your use of iostreams, you've included <iostream> and <iostream.h>, which can cause problems.
