GATE-Programming Methodology Questions and Answers
Programming methodology in C++ focuses on structured and object-oriented approaches to problem-solving using efficient algorithms and modular coding. For GATE aspirants and placement candidates, programming questions and answers on this topic often involve analyzing code behavior, debugging, and implementing logic using OOP principles like inheritance, polymorphism, and encapsulation. This section provides GATE-oriented C++ programming methodology questions with answers, enabling learners to practice concepts such as recursion, data abstraction, and error handling. Practicing these C++ questions helps in mastering both academic and placement-level programming skills.
