History of C Programming Language

History:


  • "Dennis Ritchie" is known as the inventor of C language.
  • Dennis Ritchie developed the C in 1970's in Bell laboratories, U.S.A.
  • In 1972, Ritchie started to improve B(with Ken Thompson), which resulted in creating a new language C
  • He kept most of the syntax of B Language and added the new features like data types and structures.
  • C was developed between 1971-1973, containing both high level and low-level functionalities which can develop applications as well as Operating system
  • Initially it was designed for programming in Operating system called UNIX. But now, entire UNIX OS and tools provide by it are written in C (using low level functionalities).
  • It was developed to overcome the problems of previous languages such as B, BCPL, etc. which don't understand the datatypes and structures.

Evolution of  Programming Languages:

  • 1960- ALGOL(International Group)
  • 1967- BCPL(Martin Richard)
  • 1970- B(Ken Thompson)
  • 1972/1973- Traditional C(Dennis Ritchie)
  • 1978- K & RC(Kernighan & Dennis Ritchie)
  • 1989- ANSI C(ANSI Committee)
  • 1990- ANSI/ISO C(ISO Committee)
  • 1999- C99(Standardization Committee)

Basic Structure of C Program

Image
 Structure of C Program: // single line Comments # pre-processor directives prototype declarations global variables main() function { local variable declaration statements ------      --------    ------- } user_defined_function1() { variable declaration statements -----         -----         ----- } Explanation: 1. Comments: Comments can be places anywhere in the program; generally used for documentation purposes or to increase the readability of the code. There are two types of comments 1. Single line comments        2. Multi line comments Single line comments starts with // followed by statement ex: // this is a single line comment Multi line comment start with /* and ends with */. ex: /* This is           multi line           comment */ 2. Preprocessors Directives:...
