Object-Oriented Programming (OOP) is one of the most important paradigms in modern software development and forms the foundation of many programming languages and applications. This book has been developed keeping in view the Veer Madho Singh Bhandari Uttarakhand Technical University (VMSB U.T.U.) syllabus for Object-Oriented Programming using C++ and is designed to fulfill the academic requirements of undergraduate students pursuing Computer Science and Engineering, Artificial Intelligence and Machine Learning, Information Technology, and related disciplines.

The book provides a comprehensive introduction to Object-Oriented Programming concepts using C++, combining theoretical explanations with practical programming examples. It covers fundamental concepts such as classes and objects, constructors and destructors, encapsulation, inheritance, polymorphism, abstraction, operator overloading, templates, exception handling, file handling, namespaces, and Standard Template Library (STL) concepts.

Designed with a student-centric approach, each chapter includes learning outcomes, detailed explanations, illustrative examples, program codes, sample outputs, chapter summaries, multiple-choice questions, and programming exercises to enhance conceptual understanding and problem-solving skills.

The book follows a structured approach suitable for classroom teaching, self-learning, and examination preparation. It serves as a useful textbook for undergraduate students as well as a reference guide for learners who want to develop strong programming skills in C++ and understand object-oriented design principles.

The practical examples and exercises included in this book help students bridge the gap between theoretical concepts and real-world programming applications, making it a valuable resource for both beginners and advanced learners.
