You forgot to #include <string>
你忘了 #include <string>
using std::stringwithout including it's header works on some compilers that indirectly import parts of <string>into their <iostream>or other headers but that's not standard and shouldn't be relied upon. Also they often break when you try to output a string since they only included a part of the implementation and are missing the part that implements the operator<<.
使用std::string不包含它的头文件适用于一些间接将部分导入<string>到它们<iostream>或其他头文件中的编译器，但这不是标准的，不应依赖。此外，当您尝试输出字符串时，它们经常会中断，因为它们只包含实现的一部分，而缺少实现operator<<.
