Introducing the standard C library. It mainly introduces frequently used functions.
The standard C library can be used by include the standard header.
#include <string.h>

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. |

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.
