Object Oriented Programming using C++ and Practice Tests

This course is a comprehensive guide to learn object oriented programming in c interview preparation (OOP) using C++, designed to help learners build a strong foundation in both C++ language features and object‑oriented design principles. It focuses on practical concepts, clean coding practices, and real‑world usage of OOP constructs in C++ applications.

The course starts with an introduction to C++ and walks you through essential language features such as function overloading, reference variables, operator overloading, and console input/output. You will then move into the core OOP concepts, learning how to write classes, create and destroy objects, work with member functions, static members, and implement patterns such as the Singleton class. Concepts like inline functions and friend functions are also covered.

Inheritance is explained in detail, including access specifiers, constructors in base and derived classes, types of inheritance, upcasting and downcasting, method overriding, and virtual functions. The course further explores polymorphism, pure virtual functions, and virtual base classes to help you understand runtime behavior in C++ programs.

You will also gain hands‑on experience with I/O streams and file handling, covering both text and binary file operations, object persistence, and error handling. Advanced topics such as exception handling, custom exception classes, stack unwinding, and templates (function and class templates) are included to strengthen your programming skills.

Practice tests are included to reinforce learning and validate your understanding of C++ OOP concepts.
