C++ Variables

[FinalVersion]

Lets say I have:

main.cpp

resources.h

Now the header file is included in main.cpp, how can I use variables in the header file that are declared in main.cpp? And the header file just contains functions and some data;

[FinalVersion]

Never mind, declaring the variable in the Global Scope of main.cpp, and adding extern int var, solved it.

Congratulations, you just learned how to be a bad programmer.

How about you point out my mistake, and be less of an ass about it.

• You're using global variables
• You don't know how to use global variables. I strongly doubt your code is doing what you think.

I don't know what you're trying to do, but maybe you're looking for static variables?

I think what he's looking for is more parameters for his functions.

Well if there is a better way to pass a variable from different files, main.cpp -> Header File. I'd like to hear it.

Edit: Static looks more like what I want.

We call it proper software design.

You don't pass variables from file to file. You pass arguments from function to function.

Ok, I understand that.
