The C language is a common, high-level language originally designed by Dennis Ritchie at Bell Labs to develop the UNIX operating system. The C language was first implemented on the DEC PDP-11 computer in 1972.
In 1978, Brian Kernighan and Dennis Ritchie produced C's first publicly available description, now known as the K-R standard.
The UNIX operating system, the C compiler, and almost all UNIX applications are written in C. For a variety of reasons, the C language is now a widely used professional language.
The C language was originally used for system development, especially for programs that make up the operating system. B ecause the C language produces code that runs at almost the same speed as the assembly language, the C language is used as the system development language. Here are a few examples of using C:
A C-language program, which can be three lines or millions of lines, can be written in one or more text files
can use "vi",
or any other text editor to write your C-language program.
This tutorial assumes that you already know how to edit a text file and how to write source code in a program file.
