无法创建移动阵列。

Question

我在将数组的第一个输入移动到最后时遇到问题，这样我就可以计算Window输入数的平均值。我必须使用数组（不是矩阵）来计算权重的移动平均值。问题：如果我将权重数量设置为5，输入5个权重，然后执行算术我得到第1天的正确平均值，但是，每天之后不正确。任何人都可以在这里提供指导和/或指向我允许我执行我的代码行的程序或网站，这样我就可以更有效地解决这个问题。谢谢！

#include <iostream>
#include <cstdlib>

using namespace std;

const int MAX_NUM_WEIGHTS = 50;
// Function prototypes:
void movingAverage(int& numWeights, int weightArray[], int& Window);

int main()
{
    int numWeights, Window;
    int weightArray[MAX_NUM_WEIGHTS];
    movingAverage(numWeights, weightArray, Window);

    return 0;
}

void movingAverage(int& numWeights, int weightArray[], int& Window)
{
    int i = 0, j = 0, day = 0, sum = 0, temp;
    double avg;
    cout << "Enter the number of weights: ";
    cin >> numWeights;
    cout << endl;
    cout << "Enter the weights: ";
    for(i = 0; i < numWeights; i++) {
         cin >> weightArray[i];
    }
    cout << "Enter the length of the window: ";
    cin >> Window;
    cout << endl << endl;
     while(k < numWeights - 1) {
        for(j = 0; j < Window; j++) {
            sum += weightArray[j];
         }
         avg = static_cast<double>(sum) / Window;
         day = day + 1;
         cout << day << ": " << avg << endl;
         int temp = weights[i];
         weights[i] = weights[numWeights];
         if(k >= (numWeights - 1)) {
             break;
         }
     }
 }
