identifier is undefined

I've been stuck on this one for awhile. Seemingly eliminated all bugs from my code except for this one.

the below is declared in my .h publicly

  void printDaysInCourse(string studentID);

this is privately in .h

 
Student** classRosterArray;

i then define the printsDaysInCourses function in the .cpp. I'll leave that out, unless it's needed. Here's where i run into the problem, in main, I have this:

	for (int c = 0; c < numStudents; c++)
	{
		classRoster->printDaysInCourse(classRosterArray[c]->getID());
	}

When I do this I get the error "identifier "classRosterArray" is undefined, and also "left of '->getID' must point to class/struct/union/generic type"

At that point in the code, the compiler has no idea what classRosterArray is. In a function, three kind sof objects can be seen.

1) Input parameters to the function
2) Global objects
3) Objects that were made inside that function
4) If inside a class, class member variables.

Clearly, classRosterArray is none of these. At that point in the code, the compiler has no idea what classRosterArray is.

Oh ok, I had thought it was a class member variable but I guess it isn't since it is really a pointer to an array in another class
