The history of a C language

C language is a general-purpose computer programming language, widely used. The goal of the C language is to provide a programming language that compiles, processes low-level memory, produces a small amount of machine code, and can run without any running environment support in an easy way.
Although the C language provides a lot of low-level processing features, but still maintain a good cross-platform features, a standard specification written in the C language program can be compiled on many computer platforms, and even include some embedded processors (microcontroller or MCU) and supercomputers and other operating platforms.
In the 1980s, in order to avoid the differences in C language grammar used by the development companies, a complete set of international standard grammar, called ANSI C, was set up by the American National Standards Bureau for C language, as the original C language standards.
