Why This code doesn't work?

I'm getting this error
.../Game/point.h:11: error: unknown type name 'Vector'
Point AddVector(Vector v);
^
What am I missing?

In vector.cpp Line 3 there is no class named vector1. I think you need to use some forward declarations.

This compiles for me.

@Yanson,
Thank you for your help. You are right but this didn't solve the problem. At the beginning I though because I'm using vector as a name of a class that may somehow conflict with the standard vector class, so I rename the class as vector1 but I forgot to remove it here.

@Yanson,
thank you so much. I missed this part and it worked now.
