Compare two character arrays.

This function is compatible with the following targets:

ANSI

BeOS

EMB/RTOS

Mac OS

Palm OS

Win32

#include <string.h>

int strcmp(const char *s1, const char *s2);

Parameters for this facility are:

s1	const char *	The string to compare
s2	const char *	The comparison string

The strcmp() function compares the character array pointed to by s1 to the character array pointed to by s2. Both s1 and s2 must point to null terminated character arrays.

strcmp() returns a zero if s1 and s2 are equal, a negative value if s1 is less than s2, and a positive value if s1 is greater than s2.

#include <string.h>
#include <stdio.h>

int main (void)
{
	static char s1[] = "butter", s2[] = "olive oil";
	char dest[20];
	
	if (strcmp(s1, s2) < 0)
		strcpy(dest, s2);
	else
		strcpy(dest, s1);

	printf(" s1=%s\n s2=%s\n dest=%s\n", s1, s2, dest);

	return 0;
}
Output:
 s1=butter
 s2=olive oil
 dest=olive oil
