HISTORY OF C

• In the early 1980s Bijarne Stroustrup who was
  working for Bell labs develops c.
• C was originally known as C with classes as two
  language contributed to int design.
• C is a subset of c as it is an Object Oriented
  Programming./

OOPS CONCEPT

• C is based on OOPS concept. OOPS means Object
  Oriented Programming. In this concept problem is
  looked in term of objects rather than procedure.
  All object oriented programming language has to
  the following concept in common.
• Abstraction
• Encapsulation
• Polymorphism
• Inheritance

ABSTRACTION

• Abstraction is a feature in which only essential
  details of the object are shown and non-essential
  details are ignored. Consider the example of a
  car in a car the accelerator pedal steering wheel
  and the break pedal are same of the main details
  essential for driver so these essential details
  are shown to the driver.This feature simply means
  looking for what you want.

ENCAPULATION

• Encapsulation is a feature of hiding the
  complexity at the data. Consider the example of a
  car to stop the car we just apply the break and
  we dont need the mechanism of breaking system
  .The mechanism behind breaking is encapsulated
  this features hides the implementations details
  of an object and hence also called as data
  hiding.

POLYMORPHISM

• The term polymorphism has been derived from
  Greek words ploy and morphism which means
  many and form respectively.

INHERITANCE

• Inheritances is features of creating a new class
  with the properties of an existing class with the
  properties of an existing class along with some
  additional characteristics .Unique to the new
  class for example. You inheritances some
  characteristics like your appearance language and
  certain behavior from your parents and also you
  have some additional unique characteristics this
  features is called inheritances. inheritances
  thus allows responsibility of the code in C.

INPUT OUTPUT STATEMENT

• Input output standards for i/o the process of
  sending the data to the computer is called as i/o
  and the process of display the data is called as
  output theltlt than and gtgt symbols used in the
  program are called cascading operators these are
  predefined opertors that are used for output and
  input.
• Cin with gtgtsymbol?for getting input from the
  user.
• Cout with ltlt symbol ?to display the output.
•  gtgt?extraction operation get to.
• ltlt?insertion operation put to.

CLASS

• A class is a similar to a structure data type
  but it consist of not only data elements but also
  function which are operated on data elements a
  class is a way to bind data and its function
  together.

• SYNTAX
• Class userdefined_name
• Private
• Data_type member
• Public
• Data_type member
• Member function
• The body a class is enclosed.
