C evolved from two previous languages, BCPL and B. BCPL was developed in 1967 by Martin Richards as a language for writing operating systems software and compilers. Ken Thompson modeled many features in his B language after their counterparts in BCPL and used B to create early versions of the UNIX operating system. The C language was evolved from B by Dennis Ritchie at Bell Laboratories. C uses many of the important concepts of BCPL and B while adding data typing and other powerful features. C initially became widely known as the development language of the UNIX operating system. C is available for most computers. C is mostly hardware independent.

The publication in 1978 of Kernighan and Ritchie’s book, “The C Programming Language”, enthralled to the language. In 1989, the C standard was approved; this standard was updated in 1999. C99 is a revised standard for the C programming language that refines and expands the capabilities of C, but it has not be universally adopted. It means Not all popular C compilers support C99.Here you will get C Programming Multiple Choice Questions And Answers for you next job or exam
