Lots of questions about classes in general

Jon15 (151)
Here is my program, I am pretty lost on what to do. My professor gave us the int main() part of the code and we are supposed to write the declaration and implementation section, but i am having a lot trouble doing so. What do i put in the implementation section? What am I doing wrong so far?

This is what you need. In your class you need a private section consisting of two variables to hold the type,and bt arguments, these variables will be type string,you need a constructor to accept those arguments, and you need to create the showdata method to display that data.

You need to review object oriented programming. Read that chapter in your book.(You better have one).

It doesn't compile, something is wrong with the showData part of it.
