In a program I am writing, I wrote for two classes (Coordinate, and Graph), with one of them taking the other as constructor arguments.
When I try to compile it I get the following error for Graph.cpp:

I checked the code and couldn't find anything out of the ordinary.
Here are the four class files: (Sorry if it's a lot of code to sift through.)
