Oop cocepts
This document discusses object-oriented programming concepts in C++ including data abstraction, inheritance, encapsulation, and polymorphism. It provides examples of classes, objects, and methods to illustrate these concepts. Specifically, it defines a class called CS to represent students with properties like ID and marks, and a method to calculate average. It also shows an example using an Item class to store item numbers and prices in an array to demonstrate encapsulation. The document concludes with contact details for the training organization that created the presentation.
