C++输出字符指针指向的地址

2024-08-24 20:59:13

 int main()

 {

     char *s2 = "jwdajkj";

     char *s1 = new char[strlen(s2)+];

     char *s3 = static_cast<char*> (memcpy(s1, s2, strlen(s2) + ));

     printf("%p,%p\n", s3, s1);

     cout << s3 << endl;

     cout << &s3[] << endl;

     cout << static_cast<void*>(s3) << endl;

 }

需要转换为void*指针，重载的操作符<<遇到地址会自动输出字符串
