I get the same build errors multiple times while using include guards

The header file:

Code:

#ifndef HEADERS_H
#define HEADERS_H

//Class declarations

#endif

I include this file in multiple others, but I thought this should take care of it...These are the errors I get:

Code:

Also, I'm a bit confused about all the includes, why do I have to include (for example) iostream in all the cpp files that use stuff defined therein when I've already included it in main.cpp (where int main() is)?!

You have to include in every file that uses it because .cpp files aren't compiled together; they are compiled separately.

Also, include guards can't save you from missing semicolons -- adding semicolons where they belong will save you from missing semicolons.

:/ No I removed the semicolon deliberately to show you that I get the same error more than once!!!

You want -- nay, need -- to have the same error more than once. If you don't you are so screwed. Every cpp file is compiled separately. Not related to each other in any way at all -- the linker merges the object files after everything is compiled.

Uhuh, nothing's wrong then =D Thanks!
