How to include a header to multiple cpp files?

wolfmad (2)
Hi, I've been working on this for a while now and can't seem to figure it out. I trying to recreate a mario level, so I have main.cpp, a Mario class, a Goomba class, and a Koopa class, and I need them all to have access to Initializer.h, and main to have access to all the classes too. My current solution is to have Koopa include Initializer, Goomba inlcude Koopa, Mario include Goomba, and main include Mario, in hopes that that would fix my problem of multiple redefinition errors. Here's the code
