c++ - 陷入 while 循环 c

Question

我正在为我的 C++ 类(class)做作业。在这个作业中，我需要编写一个程序，从 cin 中读取数字，然后对它们求和，当使用 while 循环输入 0 时停止。

我已经编写了代码并获得了我需要的结果。但是，我陷入了一个 while 循环，该循环继续重印结果。谁能给我一些建议，让我在打印一次结果后结束这个循环？

这是我的代码:

int main ()
{
int i(1), sum(0);
int sum2(0);
const int max(10);

cout << "Enter numbers, one per line. Enter 0 to end:" << endl;

while (i!=0)
{
    cin >> i; 
    sum += i; //add current value of i to sum
    sum2 += 1;
}
while (i==0)
{   
    if (sum < 100) // If total is less than 100
        cout << "Thank you. The total was " << sum << endl 
                 << "The total number of inputs reads: " << sum2 << endl
                 << "The total is less than 100." << endl ;
    else // Else total is greater than 100
            cout << "Thank you. The total was " << sum << endl 
                 << "The total number of inputs reads: " << sum2 << endl 
                 << "The total is greater than 100." << endl ;
}
} //End of Int Main

希望一切顺利。抱歉，我不确定如何在每行上发布数字。我还尝试将 while (i==0) 更改为 if 语句 if (i==0) 但这会在输入 0 时关闭程序。有人有帮助的建议吗？我会很感激。 ^_^

更新:对不起，我忘了提及我还必须包括一个跟踪输入数量的循环计数器，一个确定总值是小于还是大于 100 的注释，以及一个确定输入的总数。这就是最后使用 if else 语句的原因。我曾尝试取出最后一个 while 语句，因为我知道这是无限循环的原因，但是当我这样做时它不会显示结果。我将代码更改为:

int main ()
{
    int i(1), sum(0);
    int sum2(0);
    const int max(10);

cout << "Enter numbers, one per line. Enter 0 to end:" << endl;

    while (i!=0)
    {
        cin >> i; 
        sum += i; //add current value of i to sum
        sum2 += 1;
    }   
if (sum < 100) // If total is less than 100
            cout << "Thank you. The total was " << sum << endl 
                     << "The total number of inputs reads: " << sum2 << endl
                     << "The total is less than 100." << endl ;
        else // Else total is greater than 100
                cout << "Thank you. The total was " << sum << endl 
                     << "The total number of inputs reads: " << sum2 << endl 
                     << "The total is greater than 100." << endl ;

} //End of Int Main

我的输出应该是

Enter numbers, one per line. Enter 0 to end:
7
8
6
5
5
9
8
0
Thank you. The total was 48.
The total number of inputs read: 8
The total is less than 100.

i 停留在 0 并且在您退出第一个循环后永远不会改变。不要使用另一个 while 循环，只需在之后打印结果即可。
