你说找不到错误？这些你都考虑了吗？==>多组数据、星期五和其他区分吗、满200才减20、优惠券内的汽油不打折

#include <stdio.h>

int main()
{
    int t, x;
    float y;
    float order, discount, coupon, payment;
    scanf("%d", &t);
    while (t--)
    {
        discount = 0;
        coupon = 0;
        scanf("%d", &x);
        scanf("%f", &y);
        order = (8.38 * y);
        if (order >= 200)
            coupon = 20;  // 满200减20 
        if (order >= 200)
            y = y - (200 / 8.38);  // 优惠券内购买的汽油不享受折扣 
        discount = y * 0.3;
        if (x == 5)
            discount += y * 0.1;  // 周五额外优惠1毛 
        payment = order - discount - coupon;
        printf("Order amount: %.2f\n", order);
        printf("E-coupon discount amount: %.2f\n", coupon);
        printf("Discount amount: %.2f\n", discount);
        printf("Payment amount: %.2f\n", payment);
    }
    return 0;
}
