比较字符串s1和s2的前n个字节是否相等

[c]代码库

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

main()
{
	char *s1="Golden Global View";
	char *s2="Golden global view";;

	clrscr();        // clear screen
	if ( !bcmp ( s1,s2,7 ) )
		printf ( "s1 equal to s2 in first 7 bytes" );
	else
		printf ( "s1 not equal to s2 in first 7 bytes" );

	getchar();
	clrscr();
	if ( !bcmp ( s1,s2,12 ) )
		printf ( "s1 equal to s2 in first 12 bytes" );
	else
		printf ( "s1 not equal to s2 in first 12 bytes" );

	getchar();
	return 0;
}
