C++ help

I don't really know much about C++, but from a design perspective; ideally, you'd want the displayCourseData() method to return a string that the program would then output, not print the result directly. That way you could use the object's logic in other ways (such as a windows applications) without having to rewrite the class for different implementations. Not that it matters much in your current context, but it's always best to learn good design from the start
