解析的外部符号“公用：__thiscall

我已经看过，我知道有其他的答案在那里，但他们都不给我什么我要找的，所以请不要报告为‘重新发布’解析的外部符号“公用：__thiscall

我得到解析外部符号。“市民：__thiscall”错误在我的C++代码，我正要踢它窗外，只是辜负我的C++类请帮我!!!!

我支票账户头文件

#include "BankAccount.h" 
class CheckingAccount 
{ 
private: 
int numOfWithdrawls; 
double serviceFee; 
int AccountBal; 

public: 
bool withdraw (double wAmmt); 
BankAccount CA; 
CheckingAccount(); 
CheckingAccount(int accountNum); 
};

及其CPP文件

#include <iostream> 
using namespace std; 
#include "CheckingAccount.h" 

CheckingAccount::CheckingAccount() 
{ 
CA; 
numOfWithdrawls = 0; 
serviceFee = .50; 
} 
CheckingAccount::CheckingAccount(int accountNum) 
{ 
CA.setAcctNum (accountNum); 
numOfWithdrawls = 0; 
serviceFee = .50; 
} 
bool CheckingAccount::withdraw (double wAmmt) 
{ 
numOfWithdrawls++; 
if (numOfWithdrawls < 3) 
{ 
    CA.withdraw(wAmmt); 
} 
else 
{ 
    if (CA.getAcctBal() + .50 <=0) 
    { 
     return 0; 
    } 
    else 
    { 
     CA.withdraw(wAmmt + .50); 
     return 1; 
    } 
} 
}

我的BankAccount头文件

#ifndef BankAccount_h 
#define BankAccount_h 
class BankAccount 
{ 
private: 
int acctNum; 
double acctBal; 

public: 
BankAccount(); 
BankAccount(int AccountNumber); 
bool setAcctNum(int aNum); 
int getAcctNum(); 
double getAcctBal(); 
bool deposit(double dAmmt); 
bool withdraw(double wAmmt); 
}; 
#endif

我的BankAccount CPP文件

#include <iostream> 
using namespace std; 
#include "BankAccount.h" 

BankAccount::BankAccount(int AccoutNumber) 
{ 
acctNum = 00000; 
acctBal = 100.00; 
} 
bool BankAccount::setAcctNum(int aNum) 
{ 
acctNum = aNum; 
return true; 
} 

int BankAccount::getAcctNum() 
{ 
return acctNum; 
} 

double BankAccount::getAcctBal() 
{ 
return acctBal; 
} 

bool BankAccount::deposit(double dAmmt) 
{ 
acctBal += dAmmt; 
return true; 
} 

bool BankAccount::withdraw(double wAmmt) 
{ 
if (acctBal - wAmmt <0) 
{ 
    return 0; 
} 
else 
{ 
    acctBal -= wAmmt; 
    return 1; 
} 
}

我的错误：
