Principles of Object Oriented Programming
The procedural approach does not model real world problems very well. In object oriented programming (OOP), programme is designed around the data being operated upon rather than functions. It ties data more closely to functions that operate on it. It allows to break down our programmes into a number of entities called objects.
Features of OOP are:
- Emphasis is on data rather than procedure.
- Programs are divided into objects.
- Every object has its own data and functions.
- The data of object can be accessed by the functions associated with that object.
- New data & functions can be easily added whenever necessary.
- Follows bottom up approach in program design.
Objects & Classes
Objects are basic run-time entities in object-oriented systems.
Objects contain data and code for manipulating that data. A class can be used to convert an object's whole set of data and code into a user-defined data type. Objects are variables of the type class. Once a class has been defined, we can construct any number of objects within that class.
Inheritance & Polymorphism
Inheritance is a process by which we can build new classes from the old ones. The new class, referred to as a derived class, can inherit the data structures and functions of the original class (base class).
Polymorphism means the ability to take more than one form. Due to polymorphism, a single function name can handle different numbers and types of arguments.
