: I have problem getting the "Head" pointer from the "WindowList" class. the project specification said that I cannot modify the file, How can I get the pointer then? : The reason I need the "Head" pointer is that I cannot pass a member function of a class to the "Traverse" function. : Can you give me permission to change the "private" keyword in the "WindowList" class to "protected"? : Thanks! : kancheng Cao
