#include <stdio.h>

int main()
{
char str1[] = "hello world";
char str2[] = "hello world";

char *str3 = "hello world";
char *str4 = "hello world";

if (str1 == str2)
printf("same\n");
else
printf("don't same\n");

if (str3 == str4)
printf("same\n");
else
printf("don't same\n");

return 0;
}
// don't same
// same
