C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process.
A C program is divided into six sections: Documentation, Link, Definition, Global Declaration, Main() Function, and Subprograms. While the main section is compulsory, the rest are optional in the structure of the C program.
