要求用户输入2d数组并将数据存储在C中的数组中

Question

我正在编写一个代码来帮助圣诞老人跟踪街道所需的礼物数量，我正在尝试通过使用2D数组并嵌套for循环，显然这是正确的方式这样做，但程序往往在要求第二宫的孩子数量后崩溃。代码如下所示：

void distribute_presents()
{
   int houses, kids=0;
   int KidsInStreet[houses][kids];
   int i, j;
   printf("Enter the number of houses in the street?\n");
   scanf("%d", &houses);
   printf("Enter the number of kids in the street?\n");
   scanf("%d", &kids);
   for (i=0;i<=houses;i++)
   {
       for (j=0;j<=kids;j++)
       {
           printf("Enter the number of kids in house %d:\n", i+1, j+1);
           scanf("%d", KidsInStreet[i][j]);
       }
    }
     printf("The presents and their respective prices are:\n");
     for(i=0;i<=houses;i++)
    {
    for(j=0;j<=kids;j++)
    {
        printf("%d", KidsInStreet[i][j]);
    }
}
}

我认为你应该首先查询房屋和孩子的数量，然后填充2D数组：

void distribute_presents()
{
    int houses, kids = 0;
    int i, j;
    printf("Enter the number of houses in the street?\n");
    scanf("%d", &houses);
    printf("Enter the number of kids in the street?\n");
    scanf("%d", &kids);
    int KidsInStreet[houses][kids];

    for (i=0; i < houses; i++)
    {
        for (j=0; j < kids; j++)
        {
            printf("Enter the number of kids in house %d:\n", i+1);
            scanf("%d", &KidsInStreet[i][j]);
        }
    }
    printf("The presents and their respective prices are:\n");
    for (i=0; i < houses; i++)
    {
        for (j=0; j < kids; j++)
        {
            printf("%d", &KidsInStreet[i][j]);
        }
    }
}
