Strings – Character Arrays

C does not have a built‑in string type. Strings are arrays of char terminated by a null byte ('\0').

char name[6] = {'J','o','h','n','\0'}; // explicit
char greeting[] = "Hello";               // compiler adds '\0'

Standard library <string.h> offers functions like strlen, strcpy, strcat, strcmp. Always ensure destination buffers are large enough (use strncpy, strncat).
