C language is a process-oriented abstract general programming language, which is widely used in the underlying development. C language can compile and process low-level memory in a simple way. C language is an efficient programming language, which only produces a small amount of machine language and can run without the support of any running environment. Although C language provides many low-level processing functions, it still maintains the cross-platform characteristics. C language programs written in standard specifications can be compiled on many computer platforms, including embedded processors and supercomputers.
Extended data:
C language is a process-oriented computer programming language, which is different from object-oriented programming languages such as C++ and Java. The design goal of C language is to provide a programming language that can compile and process low-level memory in a simple way, only generate a small amount of machine code, and does not need any running environment support at runtime. C language is faster than assembly language in describing problems, less workload, good readability, easy debugging, modification and transplantation, and the code quality is equivalent to that of assembly language. Generally speaking, C language is only less efficient than the target program generated by assembly language code 10% ~ 20%. So C language can write system software. ?
At present, in the field of programming, C language is widely used, which takes into account the advantages of high-level language and assembly language and has great advantages compared with other programming languages. Computer system design and application program design are two major fields of C language application. At the same time, C language has strong universality and can be applied in many computer operating systems with remarkable efficiency.
