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;
}

结果为：
