#include<stdio.h>

const float price_of_lily = 3.90 ;

void main()

   int quantity_of_rose,quantity_of_lily;
   float total_price_of_rose,total_price_of_lily,total,discount_value,payment;

   printf("------------------------------------\n");
   printf("-       FLOWER FLORIST       -\n");
   printf("------------------------------------\n");
   printf("Enter amount of ROSE : ");
   scanf("%f",&quantity_of_rose);
   printf("Enter amount of Lily : ");
   scanf("%f",&quantity_of_lily);

   total_price_of_lily = quantity_of_lily * price_of_lily;
   total_price_of_rose = quantity_of_rose * price_of_rose;
   total = total_price_of_rose + total_price_of_lily;
   discount_value = total * discount;
   payment = total - discount_value;


   printf("------------------------------------\n");
   printf("-       PAYMENT RECEIPT       -\n");
   printf("------------------------------------\n");
   printf("ROSE       : $%.2f  [%.0f stalks]\n",total_price_of_rose,quantity_of_rose);
   printf("LILY       : $%.2f  [%.0f stalks]\n",total_price_of_lily,quantity_of_lily);
   printf("TOTAL       : $%.2f\n",total);
   printf("DISCOUNT    : $%.2f\n",discount_value);
   printf("------------------------------------\n");
   printf("PAYMENT    : $%.2f\n",payment);
   printf("------------------------------------\n");

   getche();
}

为什么跳出来的数字这样多？？？
