How to compile multiple C files in code blocks - c

Question

So I was originally writing my code in code blocks but when I'd try to compile it would always give me errors saying that it wasn't understanding the references i was making to functions in other files.At which point I starting using atom, but it's come to the point where I need to use he debugging tool in code blocks and I'm still getting the same errors even though my code compiles when I run it through gcc. Can someone help please?? These are the errors I'm getting.
