Help with Salary Program

[Johnny123]

Hello, so I've been having some difficulties with a C++ programming assignment. We have to create a program that calculates the Gross Pay based on factors such as social, medicare, federal taxes, and exempt/nonexempt status. I have uploaded the assignment instructions to an image hosting site below. I am not getting any errors for the program, however it is not calculating the gross pay correctly.

Hey

If it is compiling you can debug it!

First try to calculate the values manually, so you will know if they formulas are all ok. It might be possible that you will find your problem here.

If not,

You know what it would be expected after execution of every function in your program, so put breakpoints over there and execute them step by step.

Another tip, write a simple headline for every function and describe its functionality, for example, giving numerical examples for every function. This helps to make the code clear and easy to look at. It might be a good idea not to have IO inside the functions that make the calculations. Not worries at this anyway.

"Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." --Brian Kernighan
