I have a main as well but it is not in use, i wanted to fix these problems before any more show up I've been looking this over and i cant seem to find out whats wrong, Please any help is greatly appreciated, Thank you in advance.

Answer 1

You have a circular dependency. Person.h includes Employer.h which includes Person.h .

You can forward declare Person in Employer.h :

Add class Person; to Employee.h and move the #include "person.h" to Employee.cpp

What the error comes from is when the compiler goes to compile Employer.cpp (or Person.cpp it doesn't matter which one), it includes the Employer.h , which tells the compiler to include Person.h , which tells the compiler to include Employer.h , but this time the include guards kick in and it stops the contents of Employer.h being included again. So it starts to compile Person.h with no mention of Employer . Therefore it is an unknown type when it sees Employer m_employer .
