  What is the Difference Between POP and OOP? Procedure-Oriented Programming (POP) and Object-Oriented Programming (OOP) are two fundamental programming paradigms. Both have their own methodologies, approaches, and use cases. Below, we will define both paradigms, outline their key differences, and provide examples of each for better understanding.   Definition of POP (Procedure-Oriented Programming) Procedure-Oriented Programming (POP) is a programming paradigm where programs are designed around procedures or functions. It focuses on dividing the program into smaller units called functions, which operate on data. Key Features of POP: Program is divided into functions or procedures. Functions are the main building blocks of the program. Emphasizes a step-by-step procedural approach. Data and functions are separate, with functions manipulating data.   Definition of OOP (Object-Oriented Programming) Object-Oriented Programming (OOP) is a p...

  Friend Class in C++ Definition A friend class in C++ is a class that has access to the private and protected members of another class. Normally, private and protected members of a class are only accessible to the class's own methods or friends. To make a class a friend of another class, we use the keyword friend inside the class definition.   Why Do We Use Friend Classes? We use a friend class to allow another class access to private or protected members of a class without making it a subclass or adding numerous getter and setter functions.   Need for Friend Classes 1.       Access Private Data : A friend class can work directly with private or protected members of another class. 2.       Convenience : Eliminates the need for additional public methods to expose private data. 3.       Specialized Use : Useful in scenarios where two or more classes need close collaboration and ...
