Question

我在编译器中收到以下错误：

AccountDB.cpp：在成员函数'void AccountDB :: processTransactions（const char *）'中： AccountDB.cpp：89：9：错误：在'。'标记之前的预期初始化程序 inFile2.open（transactFile）; ^（胡萝卜超过期限）

这是相关功能。从这里的类似错误，我怀疑它与命名空间有关，但我不确定是哪一个。该函数应该读取事务的日期，帐号和金额，然后使用其他嵌套函数处理它。

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;

}

变量声明后有逗号：

double amount,
//           ^

将其更改为分号;。

设置ifstream，获取'错误：预期的初始化程序'。'token'
