Introduction of C Language and Features

   Basic of C language:-

   Introduction:-Here are some few points about it.

         C is a programming language developed at AT & T bell laboratory in 1972.

         It was designed and written by Dennis Ritchie.

    It allows variety of programs in small modules that means it is structural.

    It is also called middle level language.

Features of C language:-

(1)Modularity:-“It is the ability to breakdown a large modules into manageable sub modules”.

(2)Structured Programming:-Structured programming (sometimes known as  modular programming ) is a sub set of a Procedural programming  that enforce a logical structure on the program being written to make it more efficient and easier to understand and modify.

(3)Free Form Language:- Free form features let’s user write a C program form anywhere in the editor. The  user can start from  any line , any column , can leave line spacing, column spacing between any statement’s.

(4)Portability:-“The ability to port “ i.e. To install the software in different platforms is called portability.

(5)Middle Level Language:- It contains the features of both High level language and low level language.

(6)Extendibility:- It means the modules can be easily added whenever required into the existing C project.

(7)Flexibility:- It has got enough numbers of keywords/reserve words(ANSI C has 32) that can be used in any program situations.

(8)Case Sensitive:- In C, all built in keywords functions, keywords etc. are to be written in lower case only. User defined structures, variables, macros, constants functions etc. can be written either in upper case or lower case.
