The 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 the C language is to provide a programming language that can be compiled in a simple manner, handle low-level memory, produce only a small amount of machine code, and run without any running environment support. The C language descr iption problem is faster than the assembly language, the workload is small, the readability is good, and it is easy to debug, modify, and transplant, and the code quality is comparable to the assembly language.
