C Programming Language
C is a procedural programming linguistic communication. It was initially developed by Dennis Ritchie as a system programming language to write operating system. The primary features of C linguistic communication include depression-level admission to memory, simple prepare of keywords, and clean style, these features make C language suitable for organisation programming like operating organisation or compiler development.
