未聲明的標識符問題

我似乎遇到了一個奇怪的問題，以前沒有回答過的未聲明的標識符問題似乎涵蓋了它。對不起，如果我忽略了一個。未聲明的標識符問題

我正在用C++構建一個類文件，並且在我注意到在我的聲明結尾處沒有包括一個右括號之前，幾乎完成了它。但是，一旦我添加了括號和分號，我調用兩個特定變量的所有實例都會返回「未聲明的標識符」報告。

#include <iostream> 
#include <ctime> 
#include <cstdlib> 
using namespace std; 

class FerryBoat 
{ 
    //Variables 
    private: 
     int numOfPorts; 
     int startingPort; 
     int destinationPort; 
     int maximumAutos; 
     int currentPort; 
     int currentAutos; 


    //Methods 
    public: 
     FerryBoat(int, int, int); //build up 
     void moveBoat(int); //Push the ferry to it's designated station 
     int getDestinationPort(); //returns destination port 

     int getRandNum(int); //generates randomized numbers for the program 
     void loadAutos(int); //Loads cars on the port limited by the number of cars at that port. The port then has those cars subtracted from their total 
     void unloadAutos(); //Unloads cars on board 

     int getCurrentAutos(); //Returns the current number of cars on the ferry 
     int getMaxCapacity(); //returns the max number of autos able to board 
     int getStartingPort(); //Returns our start position 
     int getNumPorts(); //returns the number of ports featured 
     int getCurrentPort(); //returns our current port 
}; 

FerryBoat::FerryBoat(int ports, int capacity, int start) 
{ 
     numOfPorts = ports; 
     startingPort = start; 
     maximumAutos = capacity; 
     currentPort = startingPort; 
     destinationPort = startingPort; 
     currentAutos = 0; 

} 

void moveBoat(int nextStop) 
{ 
     destinationPort = nextStop; 
     cout<<"There are currently "<< currentAutos <<" autos loaded on the ferry."<<endl; 
     cout<<"We are now leaving port "<<currentPort<<" for port "<<destinationPort<<"."<<endl; 
     cout<<"[Movement in Progress]"<<endl; 
     currentPort = destinationPort; 
     cout<<"We have reached port "<<currentPort<<endl; 
}

沒有其他的似乎，他們都在同一地區宣佈。它是特別的「destinationPort」和「currentAutos」返回的問題，並將其與以前的代碼工作似乎沒有指出任何明顯的問題。我忽略了一些微小的東西，或者我在某處旅行並犯了一個錯誤？

如果已經得到解答，再次感謝您和appologies！

'moveBoat'不是成員函數.. 。 –

的moveBoat定義必須在FerryBoat範圍，否則它是一個非成員函數，無法獲得FerryBoat的成員：

void FerryBoat::moveBoat(int nextStop) 
{ 
    .... 
}
