- C language
Introducing the standard C library. It mainly introduces frequently used functions.
The standard C library can be used by include the standard header.
List of standard C libraries
A list of frequently used standard C libraries. Introduced by header name.
|stdio.h||Standard input / output functions, etc.|
|string.h||String operations, memory copy functions, etc.|
|stdlib.h||Memory allocation function etc.|
|stdint.h||Define integer type with size guarantee|
|float.h||Floating point type maximum / minimum values, etc.|
|stddef.h||NULL definition etc.|
Where is the standard C library implementation?
The implementation of the standard C library is implemented in each processing system, and the C compiler links it by default, so you can use it just by reading the header file.
In the case of gcc, the standard C library is implemented by a library called glibc.
C Language Function Dictionary
This is an introduction to the C language function dictionary site. The C99-compatible introduction to C language focuses on functions that are frequently used in practice, so it is very helpful if you want to know all the functions.
