C programming language

What is C language ?

It is a high level language developed by Dennis Ritchie at Bell Labs in the mid 1970s. Although originally designed as a systems programming language C has proved to be a powerful and flexible language that can be used for a variety of application from business programs to  to engineering. C is a particularly popular language of personal computers because it is relatively small - it requires less memory than other languages.

The first major program written in C was the UNIX operating system, and for many years C was considered to be inextricably linked with UNIX. Now a days C is  independent of UNIX and very important.

Although it is a high-level language, C is much closer to assembly language than are most other high-level languages. This closeness to the underlying machine language allows C programmers to write very efficient code.
