this is my first post here on stack overflow! I have used this website for years and I appreciate all of the help and time invested by everyone. It has been priceless in helping me write good code.
I get the following error message when I try to compile: "error: expected class name". I have searched the internet and I have been unsuccessful in finding a solution to my problem. I also went to "http://www.tutorialspoint.com/cplusplus/cpp_inheritance.htm" and "Single Inheritance C++ and header files" for help with inheritance and using header files. But still my problem persists and I don't know what I'm doing wrong. I have trimmed my code down to the bare bones and presented it below. Your help would be much appreciated.
