How Do I Use Header File???

[CyraxNguyen]

I've been trying to do some research about header files but I still not understand most of them. I've only known that we have to use a header file for linking program in C++. The following are the things that I need to know:
_How to use them?
_How to use ifndef, define....etc.

Thank you, Cyrax

These are pre-processor directives. They all get parsed out when you compile. An #include basically mixes 2 files together.

Here is a good tutorial...

Thank you, I understand it now.

You should probably post another topic, but post a link in here if you want me to visit.
