SYNOPSIS
#include <strings.h>
char *index(const char *s, int c);
char *rindex(const char *s, int c);
DESCRIPTION
The index() function returns a pointer to the first occurrence of the
character c in the string s.
The rindex() function returns a pointer to the last occurrence of the
character c in the string s.
The terminating NULL character is considered to be a part of the
strings.

character or NULL if the character is not found.
