i have to make the C++ program that will have the user input some test grades and exam grades and their personal info then output their stuff in the end. i have almost the whole thing done, but i would compile it throws up a list of 30 erros and i am having troble with it. i think it looks good but im still not all that good with this stuff please help. here is the code

If you see any errors ar anyway that i could get this to compile please let me know. i would really apreciate it. thanks

P.S. i also attached both the .cpp file and the compiler output tex file aswell.

Wow... Before worrying about getting it to compile, you might want to think about writing a design document to get your logic straight.

But...
Your error log tells you what is wrong. In your class declaration, you aren't referring to valid types, you are referring to your own names for things. Problem.

main isn't a void function.

You declare Grade::numExams and Grade::grades as private, and non-static, then immediately try to use them in a public fashion in main. At this point they are A) unaccessible, and B) uninitialized.

In your class, er, how many of your actual homework assignment grades get recorded somewhere? Well, all of them, but only #10 matters, since you keep overwriting the same variable. Ditto the exam grades, except there you only overwrite once.

CalcLetterGrade... er, isn't there perhaps a better method of doing this? Maybe with relational operators? And you miss the case where grade is 90.

Again, the errors list is pretty good, why not work through that from the first down, recompiling every time you fix something.

Incremental Compiles are always better than just writing a bunch of code and preying for the best.

Thanks for the help. I wouldn't have able to get it figured out without you.
