从while循环计算值？-Java 学习之路

我需要使用输入到while循环中的数据来计算总和和最大值 . 我很困惑我如何能够将每天存储为“weathervalue”的“day”用户输入，并将其用于公式之外的循环中 . 这是我的代码 .

#include <iostream>

using namespace std;

int main ()
{
double weatherdays;
double weathervalue;
double counter;
double day;

cout << "Enter the number of days for which you have weather data - ";
cin >> weatherdays;

counter = 1;
day = 1;

while (counter <= weatherdays)
{
    counter++;

    cout << "What is the rainfall for day " << day << endl;
    cin >> weathervalue;

    cout << "What is the max temp for day " << day << endl;
    cin >> weathervalue;

    day = day + 1;
}

weathervalue = //formula for sum of rainfall values entered in while loop

cout << "The total rainfall is " << weathervalue << endl;

weathervalue = //formula for max temp values entered in while loop

cout << "The max temperature is " << weathervalue << endl;

你做 not need数组来完成这个任务 . 表示当前状态的两个变量可以：

#include <iostream>

using namespace std;

int main ()
{
    int weatherdays;
    int day = 0;
    double rainfall;
    double temperature;

    double sumRainfall = 0.0;
    double maxTemperature = 0.0;

    cout << "Enter the number of days for which you have weather data - ";
    cin >> weatherdays;

    while (weatherdays--)
    {
        ++day;

        cout << "What is the rainfall for day " << day << endl;
        cin >> rainfall;
        sumRainfall += rainfall;

        cout << "What is the max temp for day " << day << endl;
        cin >> temperature;
        if(temperature > maxTemperature)
        {
            maxTemperature = temperature;
        }
    }

    cout << "The total rainfall is " << sumRainfall << endl;

    cout << "The max temperature is " << maxTemperature << endl;
    return 0;
}

您也可以使用 <algorithm> 中存在的 std 算法，但那只是一个小蛋糕！

我想你问的是如何存储所有输入的值？

使用收集，例如 vector .
```
cin >> wearhervalue;
vals.push_back (weathervalue);
```
