C language is a process-oriented computer programming language, different from C++, Java and other object-oriented programming languages.C was designed to provide a programming language that could compile easily, process low-level memory, produce only a small amount of machine code, and run without any runtime support.C describes problems faster, less effort, easier to read, debug, modify, and port than assembly language, and the quality of the code is comparable to assembly language.C is generally only 10% ~ 20% less efficient than the target program generated by assembly language code.Therefore, C language can write system software.
At the current stage, C language is widely used in the field of programming. It takes into account the advantages of assembly language of high-level language and has great advantages compared with other programming languages.Computer system design and application programming are two major areas of C language application.At the same time, C language is widely used and can be applied in many computer operating systems with remarkable efficiency.
