OOP امثاله

The document contains examples of C++ programs demonstrating various OOP concepts like classes, objects, methods, constructors, destructors, friend functions, static functions, and const objects. Some key examples include: 1. Defining classes for mobile phones and vehicles with member variables and methods to set/get prices, speeds, and areas. 2. Using constructors and destructors to initialize values and print outputs. 3. Demonstrating passing objects to methods and returning new objects. 4. Using friend functions to access private members of different classes. 5. Defining static and const qualifiers on class members and methods. The examples provide code snippets to explain concepts
