C - Language Brief History
1963 - CPL
1967 - BCPL by Mr. Martin Richards
1969 - B Language by Mr.Ken Thomson
1972 - C Language by Dennis M. Ritchie
The C programming language was developed in the year 1972 by Dennis M. Ritchie an employee from Bell Labs (AT&T).

In the 1960s Dennis Ritchie worked, with several other employees of Bell Labs (AT&T), on a project called Multics. The goal of the project was to develop an operating system for a large computer that could be used by a thousand users. However In 1969 AT&T (Bell Labs) withdrew from the project, because the project could not produce an economically useful system.So the employees of Bell Labs (AT&T) had to search for another project to work on.BCPL stands for Basic Combined Programming Language. Martin Richards developed BCPL Language.The B language is derived directly from Martin Richards BCPL by ken Thompson.

In the early days computer code was written in assembly code. To perform a specific task, you had to write many pages of code. A high-level language like B made it possible to write the same task in just a few lines of code. The language B was used for further development of the UNIX system. Because of the high-level of the B language, code could be produced much faster, then in assembly.

A drawback of the B language was that it did not know data-types. (Everything was expressed in machine words). Another functionality that the B language did not provide was the use of “structures”. The lag of these things formed the reason for Dennis M. Ritchie to develop the programming language C.

So in 1971-73 Dennis M. Ritchie turned the B language into the C language, keeping most of the language B syntax while adding data-types and many other changes. The C language had a powerful mix of high-level functionality and the detailed features required to program an operating system. Therefore many of the UNIX components were eventually rewritten in C .
