From cppreference.com
This header was originally in the C standard library as <string.h>.
This header is for C-style null-terminated byte strings.

| copies a certain amount of characters from one string to another (function) | ||
| concatenates two strings (function) | ||
| concatenates a certain amount of characters of two strings (function) | ||

String examination | ||
| returns the length of a given string (function) | ||
| compares two strings (function) | ||
