c++ - 将代码输出到 .txt

Question

我想知道如何将所有这些代码输出到 .txt 文件。当我在 80 年用 cout 替换 outFile 时，我得到了我想要的输出(月份和余额最多 61 个月)。但是，当我尝试将其放入 .txt 文件时，我得到的只是一个 "62 -11.90"

int main()
{
    int counts, month=1;
    double totalBalance, interestRate, minimumPayment, sumOfInterest= 0, minPayment, monthInterest;

    input(counts, totalBalance, interestRate, minimumPayment);


    while(totalBalance > 0)
    {
        calculate(month, totalBalance, interestRate, minimumPayment, minPayment, monthInterest, sumOfInterest);
         sumOfInterest = sumOfInterest + sumOfInterest;
         month ++;
        output(month, totalBalance, interestRate, minimumPayment, minPayment, monthInterest, sumOfInterest);
    }

}

void output(int mont, double totalBalanc, double interestRat, double minimumPaymen, double minPaymen, double monthInteres, double sumOfInteres)
{
    ofstream outFile;
    outFile.open("lab6.txt");
    outFile << setw(5) << right << mont << setw(13) << right << setprecision(2) << fixed << totalBalanc << endl;
}

Answer 1

每次打开文件时，它都会从文件的开头开始写入。

勾选可选的open mode parameter对于其他选项，例如 ate。
