C programming

C fully supports object-oriented programming, including the four pillars of object-oriented development: • Encapsulation • Data hiding • Inheritance • Polymorphism

A class constructor is a special member function of a class that is executed whenever we create new objects of that class.A destructor is a special member function of a class that is executed whenever an object of it's class goes out of scope or whenever the delete expression is applied to a pointer to the object of that class.

A class provides the blueprints for objects, so basically an object is created from a class. A class is used to specify the form of an object and it combines data representation and methods for manipulating that data into one neat package .

Many times, you are not aware in advance how much memory you will need to store particular information in a defined variable and the size of required memory can be determined at run time.

A namespace is designed to overcome the difficulty to differentiate similar functions, classes, variables etc. with the same name available in different libraries.Object slicing happens when a derived class object is assigned to a base class object, additional attributes of a derived class object are sliced off to form the base class object.

Templates are the foundation of generic programming, which involves writing code in a way that is independent of any particular type.

Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. The idea of inheritance implements the is a relationship.
