C2146缺失;在Visual Studio 2010中

Question

當我嘗試在VS 2010中進行編譯時，出現以下錯誤。它也在抱怨字符串未定義，這沒有任何意義，因爲我明確包含它。我明白了什麼錯誤的意思，但他們似乎沒有任何意義：

1>c:\users\jon\documents\visual studio 2010\projects\project 2\project 2\userfactory.cpp(11): error C2146: syntax error : missing ';' before identifier 'profession' 1>c:\users\jon\documents\visual studio 2010\projects\project 2\project 2\userfactory.cpp(11): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int 1>c:\users\jon\documents\visual studio 2010\projects\project 2\project 2\userfactory.cpp(11): error C4430: missing type specifier - int assumed.

這是我的代碼：

#include "objbase.h" //I found this recommendation while googling, but had the errors prior to adding this. 
#include <string> 
#include <map> 
#include <utility> 

class UserFactory { 
public: 
    class User { 
     char gender; 
     int id; 
    string profession;// line 11 
    int zip; 
    friend class UserFactory; 
}; 
private: 
map<int,User*>* map; 

public: 
UserFactory() : map(new map<int,User*>()) { } 

virtual ~UserFactory(void); 

void process(string s) { 
    //user id | age | gender | occupation | zip code 

} 
}; 

任何幫助，將不勝感激之前，我撕裂我的頭髮！

謝謝！

字符串是std名稱空間的一部分，所以您必須將其稱爲std :: string。這同樣適用於地圖。
