Answer 2

Can you please help me , I am completely lost.

Answer 3

Well, what problem are you having?

Answer 4

I mean, if you are in CS 202, how can you be completely lost? That class number sounds like you should have had something before this one, so you should have some idea about the code. Thus, I wonder which part it is that has you baffled.

Answer 5

I've had basic C++ but this is a brand new topic.

Answer 6

OK, so what is the new part? What is it that you are having trouble with?
