What is c programming?

C programming is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system.
Although C programming was designed for implementing system software,It is also widely used for developing portable application software.
C programming is one of the most popular programming languages of all time and there are very few computer architectures for which a C compiler does not exist. C programming has greatly influenced many other popular programming languages.
