SOAL DARI MODUL "C PROGRAMMING PROGRAM EXAMPLES"

MyJava Café wants you to write a program to take orders from the Internet. Your program asks for
the item, its price, and if overnight shipping is wanted. Regular shipping for items under $10 is
$2.00; for items $10 or more shipping is $3.00. For overnight delivery add $5.00.  For example, the
output might be:
Enter the item:
Tuna Salad
Enter the price:
450
Overnight delivery (0==no, 1==yes):
1

Invoice:
  Tuna Salad    4.50
  shipping      7.00
  total         11.50 

SOLUTION

 //menghitung harga antaran dengan syarat tertentu
#include <stdio.h>
#include <conio.h>

main()
{
    float price, shipping, total;
    int overnight_delivery;
    char item[20] = " ";
  
    printf("enter the item : \n");
    scanf("%s", &item);
    printf("enter the price : \n");
    scanf("%f", &price);
    printf("overnight delivery (0 = no, 1 = yes)\n");
    scanf("%d", &overnight_delivery);
      
        if(overnight_delivery == 1)
            {
            if(price < 10)
              {shipping = 2.00 + 5.00;
            }else
              {shipping = 3.00 + 5.00;
        }  
            }             
         if(overnight_delivery == 0)
            {
            if(price < 10)
              {shipping = 2.00;
            }else
             { shipping = 3.00;
            }
            }              
                                    
    printf("invoice : \n");
    printf("%c %.2f", item, price);
    printf(" \nshipping : %.2f\n", shipping);
    printf("total : %.2f\n", price + shipping);
  
    getch();
    return 0;
