C language Features

  • C language is a procedural language with structured programming, variable scope and recursive functions.

  • Through pointers, C language can easily perform low-level control of memory.

  • Compilation preprocessor (preprocessor) makes C language compilation more flexible.

Understand the C language

  • C is a general programming language that is widely used in system software and application software development. Between 1969 and 1973, in order to transplant and develop the UNIX operating system, Dennis Ritchie and Ken Thompson designed and developed it at Bell Labs based on the B language.

  • C language has the characteristics of high efficiency, flexibility, rich functions, strong expressiveness and high portability.

Currently, C language compilers are commonly used in various operating systems, such as Microsoft Windows, Mac OS X, Linux, Unix, etc.

  • The design of the C language has influenced many subsequent programming languages, such as C, ObjectiveC, Java, C#, etc.

  • In the 1980s, in order to avoid differences in the C language syntax used by various developers, the American National Bureau of Standards formulated a complete set of international standard syntax for the C language. , called ANSI C, as the standard for the C language. Relevant program development tools from the 1980s to the present generally support ANSIC-compliant syntax.

This is a computer language that has not been exposed for more than 40 years, and it is relatively close to the bottom level. This way you can not only learn the language itself, but also learn some more in-depth knowledge.
