Object-Oriented Programming Using C++ Language with File Handling, Exception Handling, and Standard Template Library
Introduction C++ is one of the most powerful programming languages, known for its speed, versatility, and object-oriented capabilities. In 2025, despite the rise of Python, Java, and other languages, C++ still holds a strong place in system programming, game development, competitive programming, and real-time applications. This article will help you understand Object-Oriented Programming (OOP) in C++ along with file handling, exception handling, and the Standard Template Library (STL). What is Object-Oriented Programming (OOP)? OOP is a programming paradigm that structures code around objects instead of functions. Benefits of OOP in C++: Better organization of code Reusability with inheritance Easier debugging and maintenance Closer representation of real-world problems Core Principles of OOP in C++ Encapsulation: Wrapping data and methods into a single unit (class). Inheritance: Deriving new classes from existing ones. Polymorphism: Ability ...
