[c]代码库

#include <syslib.h>
#include <string.h>

main()
{
	char *s1="Hello, Programmers!";
	char *s2="Hello, programmers!";
	int r;

	clrscr();

	r=stricmp ( s1,s2 );
	if ( !r )
		printf ( "s1 and s2 are identical" );
	else if ( r<0 )
		printf ( "s1 less than s2" );
	else
		printf ( "s1 greater than s2" );


	getchar();
	return 0;
