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 byte ('') is considered to be a part of the strings.

RETURN VALUE
