Question

Hello, I am trying to write a program using C++ that will calculateyour college GPA for you. I realize that Excel is an easier way to do this, but Ithought this would be more interesting. The goal/algorithm is of this nature: 1. Prompt for number of credit hours earned up until thecurrent semester 2. Prompt for cumulative GPA up until current semester 3. Prompt for number of classes worth credit hours that youare taking currently (here is the part I am having trouble with) 4. Based on input from 3, prompt for class name, GPA, andcredit hours for each class being taken, and only that manycalsses 5. Re-iterate entered informaiton in a table format 6. calculate current semester GPA 7. calculate cumulative GPA I know all of the formulas and what not to do thecalculations, I am just having trouble coming up with a working setof commands that will only prompt for the correct number ofclasses. It needs to be able to account for an input of 0, whichwill yield an output of only the info from steps 1 and 2, an inputof 1-8 for number of classes then prompt for only that many classescorrectly, then give an invalid error message for any value greaterthan 8. I have tried if-else functions, but they always give errormessages. Any suggestions? I realize that Excel is an easier way to do this, but Ithought this would be more interesting.
