Editor to share with you what C language refers to, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

One

C language is a general computer programming language, which is widely used in low-level development. The design goal of C language is to provide a programming language that can easily compile and process low-level memory, generate a small amount of machine code and run without any running environment support.

II.

Although C language provides many low-level processing functions, it still maintains a good cross-platform feature. C language programs written in a standard specification can be compiled on many computer platforms, even including some embedded processors (single-chip microcomputer or MCU) and supercomputers.

Three

In the 1980s, in order to avoid differences in the syntax of C language used by various developers, the American National Bureau of Standards formulated a complete set of American national standard grammar for C language, called ANSIC, as the original standard of C language. [1] at present, the C11 standard issued by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) is the third official standard of the C language and the latest standard of the C language. The standard better supports Chinese character function names and identifiers, and realizes Chinese character programming to some extent. C language is a process-oriented computer programming language, which is different from other object-oriented programming languages such as Java. Its compilers mainly include Clang, GCC, WIN-TC, SUBLIME, MSVC, Turbo C and so on.

Hello, the skillful hands of the world created the new project of C World.

Create a source file

Test.c-source file

Test.h-header header file

Main function

The first program

The printf shown in the above code is a library function, so we need to call the header file as follows

Stdio.h is the name of a header file

Std (standard) I (input) o (output)

Standard input / output header file

Run the code

Shortcut key: Ctrl + F5 or fn + Ctrl + F5

The second method is as follows:

Initial understanding of pre-knowledge of data types

A preliminary understanding of data concept

? The unit is in bytes! ?

Variables? Constant?

Some values in life are constant (for example, pi, gender (? ), ID card number, blood type, etc.)

Some values are variable (e.g. age, weight, salary).

Immutable values are expressed by the concept of constants in C language and become value by variables in C language.

The method of defining variables

Classification of variables

The use of variables

The above is all the contents of this article "what does C language mean?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
