Perhaps
也许
<string> header is missing.
Try including it.
尝试包括它。
Doctor.h
医生.h
#ifndef DOCTOR_H_
#define DOCTOR_H_
#include <string>
class Doctor{
std::string name;
public:
Doctor();
~Doctor();
};
#endif
Doctor.cpp
医生.cpp
#include "Doctor.h"
Doctor::Doctor()
{
}
Doctor::~Doctor()
{
}
Main.cpp
主程序
#include "Doctor.h"
int main()
{
return 0;
}
It is working fine. I have tested.
它工作正常。我已经测试过了。

You need to #include <string>in Doctor.h, and you need the standard namespace std::string.
您需要#include <string>in Doctor.h，并且需要标准命名空间std::string。
