C++

Object Oriented Paradigm Object Oriented Paradigm also called oop is a model for writing computer programs. Features of OOP Abstraction. Encapsulation. Polymorphism. Inheritance. Abstraction Using the essential feature of a programming language  and hiding the complexity is known as abstraction. Encapsulation Wrapping of data members & the member function within the class is known as Encapsulation. It is based on the concept of data hiding & data hiding says that we can't access the private element of class without the help of member function of that class. Polymorphism Ability to assume several forms is known as polymorphism and we can achieve polymorphism in C++ by 3 ways. By function Overloading. Operator Overloading. Virtual Function. Inheritance It is taken from the real world where the parent class is known as base class and the child class is known as derived class. It says that child class can access all property o...
