Thread: print problem

If someone could help me fix a problem with my almost done program, when i get to my function which prints out date it gets to one point of the code and an error comes up when using visual c++ 6.

This is the part of the code where the error occurs.

Code:

void Course :: printCourses(Instructor *S[], Instructor A, int index)
{
	
		if(S[index] != NULL_POINTER) 
		{
			 cout<<A.TC[index]->courseDepartment<<endl;
			 
		}
}
