Results always returning 0 and accessing classees - c++

Question

I am having a couple problems with my code.
First off, with the code like it is, No matter what information I put in, It always returns 0, Any suggestions on where to fix this and how? I believe it has something to do with my Class Employee. How would I go about fixing this?
Second, How do I access the information in int total()? I need to access it for the last bit of code.
Also if you notice anything else that I can do to optimize my program, I welcome your suggestions. I am learning C++ as I go and will always be a Student.

Hey Guys, Thanks for the help. I have most of it done now. It is displaying all the information. I am now just working on getting it to display the Employee Summary Data. I revamped my code to make it cleaner because I was trying every suggestion given to me as I learn best by hands on.

Answer 1

That's what you get for using non-initialized variables. You have set no value to your class members, you can't expect the compiler to guess what is your employee's name or total pay.
You need to use the form:
object name.member name = value

Answer 2

Of course, you should call the functions before outputting results that are supposed to be produced by these functions:
employee1.Overtime();
employee2.Overtime();
employee3.Overtime();
