Programming has evolved significantly over the years, with structured and object-oriented programming (OOP) emerging as two of the most influential paradigms. Structured programming laid the foundation for organized and efficient code by emphasizing sequential execution, modularization, and control structures like loops and conditionals. Object-oriented programming further revolutionized software development by introducing concepts such as encapsulation, inheritance, and polymorphism, enabling developers to build scalable and reusable applications. This book provides a comprehensive understanding of both paradigms, exploring their principles, advantages, and real-world applications. Whether you are a beginner looking to grasp fundamental programming concepts or an experienced developer aiming to refine your skills, this book serves as a valuable resource. It covers theoretical foundations, practical implementations, and best practices to help readers write efficient and maintainable code. By bridging structured and object-oriented approaches, this guide offers a holistic perspective on software development, preparing readers to tackle complex programming challenges with confidence.
