當我嘗試把班級分成頭，我得到當我在課堂上

Question

這裏用繩子編譯沒有發現部件的錯誤代碼：

Classes.h

#ifndef CLASSES_H 
#define CLASSES_H 
// Team Class 
class Team { 
public: 
    string title, initials; 
}; 
// End 

// Player Class 
class Player { 
public: 
    int skill, cost; 
    string name; 
}; 
// End 

// Coach Class 
class Coach { 
    int cash, cost, players; 
public: 
    string name; 
    void set_values (int, int); 
    int total (void) {return (cash - cost);}; 
}; 
// End 
#endif 

類。 CPP

#include "Classes.h" 
// Set Total Cash for Coach 
void Coach::set_values (int a, int b) { 
    cash = a; 
    cost = b; 
} 
// End 

Main.cpp的

#include <iostream> 
#include <string> 
#include "classes.h" 

---

當我編譯它沒有找到縮寫成員或名稱成員，即字符串。爲什麼以及如何解決這個問題。

即

main.cpp:22: error: ‘class Player’ has no member named ‘name’ 
main.cpp:28: error: ‘class Coach’ has no member named ‘name’ 
main.cpp:29: error: ‘class Coach’ has no member named ‘name’ 
main.cpp:30: error: ‘class Player’ has no member named ‘name’ 
main.cpp:35: error: ‘class Team’ has no member named ‘title’ 
main.cpp:36: error: ‘class Team’ has no member named ‘title’ 
main.cpp:38: error: ‘class Team’ has no member named ‘initials’ 
main.cpp:39: error: ‘class Team’ has no member named ‘initials’ 
main.cpp:40: error: ‘class Player’ has no member named ‘name’ 
main.cpp:40: error: ‘class Team’ has no member named ‘title’ 
main.cpp:41: error: ‘class Team’ has no member named ‘initials’ 
main.cpp:41: error: ‘class Player’ has no member named ‘name’ 
main.cpp:41: error: ‘class Coach’ has no member named ‘name’ 

或者 在文件中包含從main.cpp中：9：

classes.h:7: error: ‘string’ does not name a type 
classes.h:15: error: ‘string’ does not name a type 
classes.h:23: error: ‘string’ does not name a type 

請幫幫忙！我是新手，所以它可能是我無法做的或者簡單的修復。

Answer 1

你需要使用std::string完整的資格和#include <string>到你的頭文件。

Answer 2

您需要#include <string>在classes.h文件中並將string變量聲明更改爲std::string。 例如：

class Team { 
public: 
std::string title, initials; 
};
