本来不想写这题的，但是想想最近沉迷玩雨世界，班长又问我这题，就草草写了一下

代码如下：

#include<stdio.h>
#include<math.h>
struct parking{
    int distance;
    int remain;
    int speed;
    int time;
    int jud;
}parking[50];
void input(int n);

int main(void)
{
    int n, area = 0, min_d = 1000000000;
    scanf("%d", &n);
    input(n);
    //处理
    for(int i = 0; i < n; i++)
    {
        if(parking[i].speed > 0 || (parking[i].speed == 0 && parking[i].remain))
            parking[i].jud = 1;
        else if(parking[i].remain + (int)round(parking[i].speed * parking[i].time / 10.0) > 0)
            parking[i].jud = 1;
        else
            parking[i].jud = 0;
    }
    //得到最小并输出
    for(int i = 0; i < n; i++)
        if(parking[i].jud && parking[i].distance < min_d)
            area = i + 1, min_d = parking[i].distance;
    printf("%d", area);

    return 0;
}
void input(int n)
{
    for(int i = 0; i < n; i++)
        scanf("%d", &parking[i].distance);
    for(int i = 0; i < n; i++)
        scanf("%d", &parking[i].remain);
    for(int i = 0; i < n; i++)
        scanf("%d", &parking[i].speed);
    for(int i = 0; i < n; i++)
        scanf("%d", &parking[i].time);
    return;
}

简单的struct结构运用，没啥好说的
