建立一個ifstream的，得到。「的錯誤：之前預計初始 '令牌'

Question

我在編譯器收到以下錯誤：

AccountDB.cpp：在成員函數「void AccountDB :: processTransactions（爲const char * ）'： AccountDB.cpp：89：9：error：expected initializer before'。'token inFile2.open（transactFile）; ^（胡蘿蔔過期）

這是相關功能。從這裏的類似錯誤，我懷疑它與命名空間有關，但我不確定是哪一個。該函數應該讀取日期，帳號和事務數量，然後使用其他嵌套函數對其進行處理。

void AccountDB::processTransactions(const char* transactFile) 
{ 
//set up the input stream from the text file 
ifstream inFile2; 
//set up the variables to be read from text file 
char date[6]; 
char type; 
char accountnumber[20]; 
double amount, 

//open the file 
inFile2.open(transactFile); 
//standard check for file and exit if it doesn't exist 
if(!inFile2) 
{ 
    cout << "Error, input file could not be opened.\n"; 
    exit(1); 
} 
//Creates a header for listing transactions 
cout << setw(5) << "Date" 
    << setw(25) << "Account Number" 
    << setw(5) << "Type" 
    << setw(8) << "Amount" 
    << setw(30) << "New Balance" 
    << endl; 
    inFile2 >> date; 
    while (inFile2) 
    { 
     inFile2 >> accountnumber >> type >> amount; 
     cout << setw(5) << date 
      << setw(25) << accountnumber[20] 
      << setw(5) << type 
      << setw(8) << amount; 
     int relevantAccount = searchForAccount(accountnumber); 
     if (relevantAccount != -1) 
     { 
      if (type == 'P') 
      { 
       credArray[relevantAccount].processPayment(amount); 
       cout << setw(30) << credArray[relevantAccount].getBalance() << endl; 
      } 
      else 
      { 
       bool chargestatus = credArray[relevantAccount].processCharge(amount); 
       if (chargestatus = 1) 
        cout << setw(30) << credArray[relevantAccount].getBalance() << endl; 
       else 
        cout << "Credit limit exceeded" << endl; 
      } 
     } 
     else 
      cout << "Invalid account number" << endl; 
     inFile2 >> date; 
    } 
    cout << "End of transaction list." << endl; 

}

你有一個逗號的變量聲明後：

double amount, 
//   ^

修改成一個分號;。
