Debugging C++ Application

Hello all, I am dabbling in C++ and am learning how to make some applications. The project in my workbook that has me stuck is a program that calculates gross pay for a one month, 4-week period. I have written the bulk of this program and its working, but this is what I require assistance with: -Double check that my mathematics are correct (I often make silly mistakes) -I am having difficulty making a loop that will repeat a section if a user made an error, then breaks once the user is ready to move on. -Meaningful and simple comments that describe the reasoning behind the changes I'm not understanding what I'm doing wrong, so I will greatly appreciate someone who is willing to help me out. I will give you more details about specifically where I am wanting the loop to be placed once I agree to award you this project. Thanks in advanced!
