How to use my .h file in my spearate .cpp file?

[Alex Schultze]

I've been getting back into programming, specifically c++, and I have a question about using some old class files I had made. How do I use them in a normal program? I have my class files named filename.h (not actually filename) so when I get to the main program I tried using the #include <filename.h> but it doesn't seem to work.

What errors do you get?
You have to be careful about about what you put in header files, e.g. putting member function definitions (code) can lead to multiple definitions at link time etc.

#include <filename.h> tells the preprocessor to look for filename.h in ne of the "standard places".

These "standard places" are a series of filepaths you have specified as to where yur header files are located.

Look in yur compiler documentation about how to specify additional include directories.

Or alternatively use #include "filename.h" which in most implementations is defined as searching the same directory as the current file and then the same list of standard places searched by #include <filename.h> for the file.
