strcmp, strncmp -- compare strings
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
int
strcmp(const char *s1, const char *s2);

strncmp(const char *s1, const char *s2, size_t len);
DESCRIPTION
The strcmp() and strncmp() functions lexicographically compare the nul-terminated strings s1 and s2.
RETURN VALUES
The strcmp() and strncmp() return an integer greater than, equal to, or less than 0, according to whether the string s1 is greater than,
equal to, or less than the string s2. The comparison is done using unsigned characters, so that '200' is greater than '
