Object oriented programming with c++
This document contains a quiz on object-oriented programming concepts in C++. It includes multiple choice questions that test understanding of key OOP concepts like classes, inheritance, encapsulation, polymorphism, and operator overloading. The questions cover defining and using classes, communicating between objects, reusability through inheritance, and security through encapsulation.
