A class, as referred to in C++ programming, is a variable that can contain multiple values and provides ways of interacting with those values to a program (such as setting/retrieving those values). They are defined by the programmer, but there are pre-designed classes available in some devlopment packages.
Libraries are pre-compiled functions that perform utilities for programs. The idea is that you save space by sharing common routines among multiple programs. If you're familiar with DLLs from windows, that's basically what libraries are. Your program can access those functions/routines when the program is run without requiring you, as the programmer, to implement them inside your program.
