Polymorphism

In OOP terms, polymorphism represents the ability to resolve a reference to an object’s method at run time. Specifically, different objects could make a call to a Draw or Print method, and these methods would act differently with each object; the process can take different forms behind a common interface. One of the benefits of polymorphism is that because the interface is common to objects, any object is able to respond differently to some common set of tasks, and objects are independent of each other.

Standard Template Library

The STL (Standard Template Library) was originally a third-party library from HP and later SGI, before its incorporation into the C++ standard. The standard does not refer to it as “STL”, as it is merely a part of the standard library, but many people...

Objects

Structured programming only deals with procedures (functions) and variables. The basic idea behind the Object Oriented Programming is that it deals with the objects. In real life everything is an object and every object has properties and functionality. As everything...

Classes

If we say that a particular programming language is Object Oriented then it means, the programming language must have the facility to define classes in it. A class is an expanded concept of a data structure i.e instead of containing data only, it can contain both data...

Inheritance

In real life inheritance is what we acquire from our parents. For example our lifestyle, way of talking etc… In Object Oriented Programming Inheritance is the process by which objects of one class acquire the properties and functionality of objects of another...

Object Oriented Programming Techniques

Any program which uses these five methodologies or any of it, we can call that program object oriented. They are Encapsulation, Data Hiding, Overloading, Polymorphism, Inheritance. Any programming language which supports all of these features and facilitate the programmer in developing the program in these methodologies is called Object Oriented Programming Language i.e. C++, Java, C#.
