C++ Variables


Recommended Posts

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;

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

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

We call it proper software design.

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