未定義的符號：黨:: getArrival（）

-1

我對party類稱爲party.h一個頭文件：在party.cpp未定義的符號：黨:: getArrival（）

#ifndef party_h 
#define party_h 

#include <iostream> 

class party{ 
private: 
    int people; 
    int waitTime; 
    bool waiting; 
    int arrival; 

public: 
    party(); 
    party(int, int); 
    int getPeople(); 
    void setPeople(int); 
    bool isWaiting(); 
    void setWaiting(bool); 
    void setWaitTime(int); 
    int getwaitTime(); 
    void setArrival(int); 
    int getArrival(); 
    int getTotalTime(int); 
    void decrement(); 
}; 

#endif

及其實施：

#include "party.h" 

party::party(){} 

party::party(int numPeople, int a){ 
    people = numPeople; 
    arrival = a; 
} 
int party::getPeople(){ 
    return people; 
} 

void party::setPeople(int p){ 
    people = p; 
} 

bool party::isWaiting(){ 
    return waiting; 
} 

void party::setWaiting(bool w){ 
    waiting = w; 
} 

void party::setWaitTime(int t){ 
     waitTime = t; 
} 

int party::getwaitTime(){ 
    return waitTime; 
} 

void party::setArrival(int a){ 
    arrival =a; 
} 

int party::getTotalTime(int current){ 
    return (current-arrival); 
}

每當我建該項目我收到下面的錯誤信息，

這是一個新的錯誤消息，因爲它在今天早上/本週末在Visual Studio中工作。但是自那時以來，我已經改變了大量的代碼，要點中的代碼已經更新，並且正在與我一起工作。我目前正試圖讓它在xcode中生成，這樣我就可以完成我今晚計劃的項目的調試/編程。任何幫助是極大的讚賞！謝謝！

未來，請在您的問題中發佈相關代碼，而不是鏈接到它。它可能會幫助你首先創建一個[SSCCE]（http://sscce.org/）。 – 2013-04-22 22:07:26

您沒有在您的party.cpp文件中定義getArrival。您可能想要：

int party::getArrival(){ 
    return arrival; 
}
