What is C Programming?

C is a general-purpose programming language developed in the year 1972 at Bell telephone laboratories (AT&T) by Dennis Ritchie.

Evolution of C Programming

ALGOL is the first programming language to use block structure and it is introduced in the 1960s. In 1967, Martin Richards developed a language called BCPL (Basic Combined Programming Language) which was mainly used for writing system software. In 1970, Ken Thompson developed a language called ‘B’ based on the features of BCPL which was used to create early versions of UNIX.
 
In 1972, Denies Ritchie developed the Traditional C language based on the features of ALGOL, BCPL, and B together with the features of data types and some powerful features. In 1983, the American National Standards Institute (ANSI) established a committee to define a standard for C. In 1990, the International Standards Organization (ISO) approved ANSI C.

It consists of a set of comments that gives details about the program.

Preprocessor directives
These are standard libraries that the program communicates at the time of execution. The header files are included in this section.

Global Declarations
These variables can be used in any function which is common to both the main block and function section. These are declared next to the preprocessor directives.
Function Declarations

This function is declared inside the main function. This is an optional one.

Main function

The main function is the starting point of the program execution, independent of its location within the source code. It is an essential part of the C program. The word main is followed in the code by a pair of parentheses (()) which is followed by a pair of curly braces. It is the body of the main function, where we can write the coding.
