Accessing File in C++

[cmh0114]

I'm trying to build a simple program where a user can enter numbers into the program and save it to a file. Then, they can come back later, enter new numbers into the same fields, and the program will put the new numbers into a separate file, then compare them and find the differences between cell X in file 1 and cell X in file 2, then display that. Can anyone help me or give me an example of that?
