CS304 Object Oriented Programming is a core foundational computer science course in the Virtual University curriculum, engineered to equip undergraduate scholars with advanced software engineering design methodologies, robust code reusability patterns, and mastery of modern C++. Grounded in classical references including C++ How to Program by Deitel & Deitel and Object-Oriented Programming in C++ by Robert Lafore, the course transitions students from procedural programming to the object-oriented paradigm. Students begin by exploring foundational OO concepts: mental models, real-world abstraction, objects, classes, information hiding, encapsulation, and interface design. The curriculum delves into class mechanics, member functions, inline methods, constructors, constructor overloading, copy constructors, shallow vs deep copying, destructors, the this pointer, member initializer lists, constant member functions, and static data members and methods. Students analyze object relationships including simple association, composition (has-a), aggregation, and friend functions. Operator overloading is comprehensively explored, including arithmetic operators, relational operators, assignment operator (resolving self-assignment bugs), stream insertion (<<) and extraction (>>) operators, subscript ([]) operators, function call (()) operators, and prefix/postfix increment/decrement. In inheritance and polymorphism, the syllabus covers generalization, specialization, public/protected/private inheritance, constructor chaining in class hierarchies, method overriding vs overloading, virtual functions, dynamic binding (vtable/vptr), pure virtual functions, abstract classes, multiple inheritance, and diamond virtual base classes. Advanced modules cover generic programming with function and class templates, template specialization, Standard Template Library (STL) containers (vector, list, deque, map), iterators, and robust exception handling via try-catch blocks and stack unwinding. Supported by official VU course handouts, solved past examination papers by Moaaz and Waqar Siddhu, and chapter-wise solved practice MCQs, CS304 thoroughly prepares students for university evaluations and professional software development.
