struct § Intro to Object-Oriented Programming (OOP) § Allows us to abstract at a higher level to build entities more complex than short, long, int, float, double, char, and bool § With it programmers can create their own types to define what should make up a student, a class, a department, a university, etc. http: //cs. mst. edu
