     C Programming Introduction

The C is a general-purpose, procedural, imperative computer programming language.

C is a third generation language or middle level language .It is structured programming language. It is designed and developed by Dennis M. Ritchie at AT & T’s Bell labs of USA in 1972.

C was originally implemented on the UNIX operating system on the DEC PDP-11, by Dennis Ritchie.

This was varied and modified until a standard was defined by Brian Kernighan and Dennis Ritchie in 1978 in "The C Programming Language”

 

Initially C language was used for developing system programs, particularly the programs which make-up operating systems. C is preferable language because of the reasons given below:

Easy to learn

Portability

Speed of compilation

Flexibility

Function rich libraries

Efficient use of pointer

 Advantages Of  C Language :

We can compile and execute C program in any operating system

C is a middle level language, so it combines the features of both Low levell language and High level language. (array, pointer, etc.)

It is very efficient language and is best for developing system softwares.

C language support good graphics

 

Disadvantages of c Language :

C does not support object oriented programming (OOPs) support. So to overcome C++ language. introduced

C language has no run time checking mechanism.

C language has no strict type checking.

C language does not support exception handling.

Difference Between C and C++ :

                                                                                     

C

 C++

C is Procedural Language C++ is non Procedural i.e. Object oriented Language
No virtual Functions are present in C The concept of virtual Functions are used in C++.
In C, Polymorphism is not possible The concept of polymorphism is used in C++.Polymorphism is the most Important Feature of OOPS
Operator overloading is not possible in C  Operator overloading is one of the greatest Feature of C++
Top down approach is used in Program Design Bottom up approach adopted in Program Design.
No namespace Feature is present in C Language Namespace Feature is present in C++ for avoiding Name collision.
Multiple Declaration of global variables are allowed  Multiple Declaration of global variables are not allowed.
     In C 

scanf() Function used for Input. 

printf() Function used for output

In C++
Cin>> Function used for Input.

 Cout<< Function is used for Output
