Problems with declarations

Syre Lancaster (8)
Hello everyone. I'm writing a program that uses a binary tree to hold student info such as GPA, name and ID number, Problem is I've run into some issues with declarations and could use some help.

	}
	else
	{
		cout << "That Student was not found.\n\n";

	system ("pause");

I believe the issue lies in my Student.h but I can't seem to put a pin in what went wrong.
Edit: I'm using a binary tree header as well, but haven't included in due to length. I can provide it if necessary, but I tested it with another program and it seems to work fine.

What "issues"?
coder777 (8439)
on line 21 you trying to use the incomplete type StudentInfo
why do you want to make BinaryTree a friend?

on line 12/68: the operator is defined as both friend and not friend
