Question

我正在尝试使此“ do while”循环运行3次，然后在“ do while”循环内的while循环内显示累加器中包含的数量。

似乎在正确计数，但仅在第一个循环上运行while循环。运行时，它不会继续询问下一组数字，而只是显示第一批（正确累加）。我尝试过切换一些代码并搜索google，但找不到答案。

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
    int storeNum = 1;
    int payRollAmount = 0;
    int totalPayroll = 0;

    do
    {
        cout << "Store " << storeNum << ":" << endl;

        while (payRollAmount <= -1)
        {
            cout << "Enter Store's Payroll Amount (-1 to exit): ";
            cin >> payRollAmount;

            totalPayroll += payRollAmount;
        }

        storeNum++;
    } while (storeNum <= 3);

    cout << "The Total Payroll is: " << totalPayroll << endl;

    system("pause");
    return 0;
}

The code should take in an unknown amount of "payrolls," allow you to exit using -1, and then continue on to the next stores payrolls. It should do this 3 times, and then display the total amount (all numbers entered added together.

嗨，也许每次迭代都重置payRollAmount？这样，它将继续请求输入。

for (int amount = 0; amount != -1; ) {
    cout << "Enter Store's Payroll Amount (-1 to exit): ";
    cin >> amount;
    totalPayroll += amount;
}

如何在C ++中将计数器与“ do while”循环一起使用？
