Need someone help!!!

I have the files of my program as following:
main.cpp
employee.cpp
fullTime.cpp
partTime.cpp
employee.h
fulltime.h
partTime.h
I've got so much link errors of this program.
What's the problem of them?
Thanks for anyone's help!!

Did you check the header file names of the preprocessor as it is case-sensitive?

gogo

I gave you a pointer safe class for your employ class yet you rip the guts of the memory management from it.Are you some sort of idiot. You have a char* that points at nothing and you are storing data there. In the constructor you must allocate memory to your pointer so you have some where to actually store data.Also remember that as you are dealing with a pointer to a dynamically allocated chunk of memory you must write a copy constructor and an assignment operator because the default compiler produced functions only do a bitwise copy which would mean you would end up with two objects that pointed at the same piece of data rather than a copy. This is an explosion waiting to happen.
Go back to your other post and look at the code i gave you.I only wrote the most important functions for you so that you could see how the memory was managed in your class. If there is something you dont understand then dont hesitate to ask.

Thanks a lot
I will go check the problems of my program again

Link errors
I got the link errors as the following:

How can I solve these link errors?

Hi Joy,
Is your program running properly now?

in parttime.cpp and fulltime.cpp it should be

#include "Employee.h"

not

#include "Employee.cpp"

Then I think you might want to review how class inheritance, virtual functions, and overloading functions relate to one another.

drop #include "Employee.cpp" from fulltime.cpp. The Employee.cpp file will be linked by the line #include "Employee.h" in fulltime.h. Drop #include "Employee.cpp" from parttime.cpp for same reason. Add #include "Employee.h" to parttime.h.
