How to include a file from another folder?

Question

In my current project I have separated my class files and my header files. My project structure currently looks like this:

• Project

• • Source

Answer 1

Assuming you want class1.cpp to include class1.h you would do something like this

#include "../../Header/class1.h"

The .. tells the tells the OS to jump 1 directory up when the compiler asks for the file.
