event only numbers?

computernerd89 (12)
Okay, I'm trying to do a lot of my labs for my C++ class because I'm a little behind so please try to answer.. I can ask tomorrow in class but just wanting to know what this means so I can get it done tonight. My professor gave us half of a program with these examples:

Part A. A counter controled while loop
Part B. Sentinel/Event controled while loop loop
Part C. Sentinel/Event controled loop -break out within the loop

basically gave us a model of each..which I get all these loops, but then there is the part he wants us to do which matches his set:

Part A. Write a counter-controled while-loop to process only event numbers
Part B. Write an event-controled while-loop to process only event numbers
Part C. Write an event-controled while-loop to process only event number This breaks within the loop

I don't understand the "process only event numbers". What numbers are these? I'm sorry if this is a dumb question, I actually thought he meant even numbers at first but I don't think so.. Can anyone please help me?

Lol, thats what I thought too >.>

Ummm...I'm just guessing but, maybe the numbers that are inputted to the program? If you have the code that he gave you, it might help us.

Sorry.. I should have posted that first but I don't think it has much on it.. It took me like an hour to fix all the problems his part had.. I hope he did that on purpose.. I couldn't even run it when I tried to test it.. :/ I really want to know what he means about event numbers because this program and the next two are the same, except he changes the types of loops to for, and do-while..

I figured it out.. It was "process only even" numbers.. It took about an hour to correct all the mistakes his part originally had so I'm not surprised he typed in event instead of even in all 3 projects, 3 times in each one!! Sorry about that.... :)
