History of C
History of C language :- C programming language was developed to be used in UNIX operating system. C language was developed in 1972 by "Dennis Ritchie" at bell laboratories of AT&T (American Telephone & Telegraph), that is placed in America (USA).
The origin of C is closely tied to the development or implementing of Unix operating system. Unix operating system originally implemented in assembly language on a PDP-7 by Dennis Ritchie and Ken Thompson.
Eventually, Dennis Ritchie and Ken Thompson decided to port the operating system to a PDP-11 after discussing with other developers of Unix operating system.
The original PDP-11 version of Unix was developed in Assembly language. Assembly languages are low-level programming languages that are specific to a particular computer architecture.
The developers of Unix operating system were considering rewriting the system using the B language, However B's inability to take advantage of some of the PDP-11's features, these things, led to C language. The name of C language was chosen simply as the next after B.
The development of C language started in 1972 on the PDP-11 Unix operating system. In 1972, a large part of Unix operating system was rewritten in C language. the C language had become powerful enough that most of the Unix kernel was written in C language.
