在C ++头文件中声明向量

Question

I am having some trouble with vector declarations in the header file of a C++ class I am making. My entire header file looks like this:

#ifndef PERSON_H
#define PERSON_H

#include "Message.h"
#include <string>
#include <vector>


class Person {

public:

 Person() {};
 Person(std::string emailAddress);

private:

 vector<Message> inbox;
 vector<std::string> contacts;
 std::string emailAddress;

};

#endif PERSON_H

My error occurs on the lines following the "private" declaration (where I declare my vectors). The error I am getting is C4430 - missing type specifier and and C2238 - unexpected tokens preceding ';'

Thank you for any help.

Answer 1

你错过了命名空间：

std::vector

Answer 2

你需要把'std ::'放在'vector'之前，就像你对string一样。

Answer 3

在我的情况下，添加命名空间不起作用，但是，我错过了

#include <vector>;
