First of all - stop using goto everywhere. You'r logic isn't advanced
enough to need it.
Second - it isn't enough to do
char* quizName = new char;
cin.getline(quizName,123);
new char allocates a single character! If you want a string, you should
either usse "new char[<my_string_length>] or look into the string class.
As long as you do "new char;" you can't expect _any_ part of your program
to work!
