* Introduction of c programming:
1. C is a programming language developed at AT&T's Bell laborratories of USA in 1972.
2. C was designed and written by a man named Dennis Ritchie.
3. It is structured,high level,machine independent procedure oriented language.
* History of c programming:
1. Root of all modern language ALGOL,a block structured language,introduced in early 1960's.
2. In 1967,Martin Ritchards developed a language called BCPL(Besic combined programming language) primarily for writing system software.
3. In 1970, Ken Thompson created a language using many features of BCPL and called B. It was used to create early versions of UNIX operating system.
4. C was evolved from ALGOL,BCPL and B by Dennis Ritchie at the Bell and laboratories in 1972.the c language was become more popular after publishing the book "The c programming language"by Brian Kerningham and Dennis Ritchie in 1978.
5. In 1983,American National Standards Institude (ANSI) appointed a technical committee to define a standard for c.The committee approved version of c (ANSIC) in 1989.It was also approved by the International Standareds Organization (ISO) in 1990.This version is also referred as c89.
6. C++ added several new features to c to make it now only a true object-oriented language but also a moreversatile language.during the same period,sun microsystem of USA created a new language java modeled on and c++.
7. The standardization committee of c felt that a few features of c++/java,if added to c,would enhance the usefulness of the language.The resultant c was c99,in 1999.
