Please help! c++

[Romina_1]

Hi guys! I'm new in c++ so i really need your help. I have to do a project Student Course Registration. I have to do a program where students can insert their id name and course. I have to use classes in c++

[rproffitt]

The neat part of the web today is that many systems and code is on the web. While students should write their own stuff, if you need an app you can modify then start with research like https://www.google.com/search?q=Student+Course+Registration&ie=utf-8&oe=utf-8#q=Student+Course+Registration+in+c%2B%2B

To OP. OK you dumped how many hundred lines of code and ask to fix the errors but didn't list the errors.

Ask yourself if others will have the same compiler, settings, IDE and more. Try sharing the first error and see if others can point out why.

PS. Why does your code look so much like http://www.cplusplus.com/forum/beginner/6840/ ?
If you re-use code, cite source, etc.

Don't expect us to flea out ALL "your" code.
Be specific on this line is this error message, on that line I have that problem.
Don't tell us you have errors or it does not work.
We know it doesn't, just be specific with your question if you hope to get an answer!
