What does \0 stand for in C language?

"\0" represents "string terminator" in C language. The ASCII code of "\0" is "0", which is the null character; strings always use "\0" as the terminator of the string; therefore, when a string is stored in an array, the terminator "\0" is also used. 0" is stored in the array and used as a sign of whether the string ends.

\0 represents the end of the string in the C language

\0 represents the end mark of the character string

Strings always end with '\0' as the terminator. Therefore, when a string is stored in an array, the terminator '\0' is also stored in the array, and is used as a sign of whether the string ends.

Extended information:

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

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

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 American national standard syntax for the C language, called ANSI C. As the original standard of C language.

Currently on December 8, 2011, the C11 standard released by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) is the third official standard for the C language and the latest standard for the C language. This standard It better supports Chinese character function names and Chinese character identifiers, and realizes Chinese character programming to a certain extent.

C language is a process-oriented computer programming language, which is different from object-oriented programming languages ​​such as C and Java.

The compilers mainly include Clang, GCC, WIN-TC, SUBLIME, MSVC, Turbo C, etc.
