一个简简单单的问题

#include <stdio.h>

int main()

{

    char str1[] = "abc";

    char str2[] = "abc";

    const char str3[] = "abc";

    const char str4[] = "abc";

    char *str5 = "abc";

    char *str6 = "abc";

    printf("%d\n",(str1 == str2));

    printf("%d\n",(str3 == str4));

    printf("%d\n",(str5 == str6));

}

猜猜最后答应的结果是什么？
