Object-Oriented Programming Review
Questions
Course Introduction
Object-Oriented Programming (OOP) is a foundational course that introduces students to the principles and methodologies of designing and building software using the object-oriented paradigm. The course covers core concepts such as classes, objects, inheritance, encapsulation, and polymorphism, enabling students to develop modular, reusable, and maintainable code. Through a series of hands-on projects and assignments, students gain practical experience in implementing object-oriented solutions to real-world problems using a modern programming language. The course also emphasizes best practices in software development, including debugging, testing, and documentating object-oriented applications.
