Question

有谁知道为什么这会一直崩溃，当我添加平均值时它开始崩溃。如果有人知道请帮助我编码新手，这对我来说很复杂，谢谢

#include <iostream>
#include <vector>
using namespace std;
int main()
{
    int integers;
    int average;
    int sum = 0;
    vector<int> numbers;
    cout << "Please enter in integers and enter 0 to stop: ";
    while (cin >> integers) {
        if (integers == 0) {
            sum = sum + integers;
            break;
        }
        numbers.push_back(integers);

    }
    int y = numbers.size();
    for (int i = 0; i < y; i++) {
        cout << numbers[i] << " ";
        average = (sum / integers);
        cout << "The average is: " << average << endl;
        return 0;
    }
}

当您到达for 循环时，integers 变量的值为0。在此声明中：

average = (sum / integers);

您除以0 从而导致undefined behavior 和/或异常取决于实现。话虽如此，您没有正确计算 sum 或 average。
