据说，能把这个字符串题目做对的人，有，但寥寥无几！

#include <iostream>
using namespace std;

int main()
{
char str1[] = "123";
char str2[] = "123";
cout << (str1 == str2) << endl;

char *str3 = "123";
char *str4 = "123";
const char *str5 = "123";
char const * str6 = "123";
char * const str7 = "123";
cout << (str3 == str4) << endl;
cout << (str3 == str5) << endl;
cout << (str3 == str6) << endl;
cout << (str3 == str7) << endl;

return 0;
}
