I was working on a very simple c++ program and successfully compiled 2 classes, one a subclass of the other. However when I used them in my main, i got this compilation error. Im relatively new at C++ so I dun really understand whats going on:confused:

In file included from overdraft.h:1,
from main.cpp:3:
bankAcct.h:1: error: redefinition of `class BankAcct'
bankAcct.h:1: error: previous definition of `class BankAcct'

Are you using include guards to avoid including bankAcct.h twice?

:o Indeed I was. Thanks alot for pointing that out. Didn't realise it would get me an error, got lots to learn lol.

Generally with a .h file, your file will look something like this:

#ifndef __myfile_h
#define __myfile_h

/* code
more code
end code */
#endif

The tells the compiler to only include the header information once.

In some compilers, a simple #pragma once at the top will do the trick too.

Dev-C++ has an "add library" (if it's a project file).
Alt + P I believe.
