Question

In C using (printf and scanf)

Write a program to ask the user for the weight of a package, and display the shipping charges for the package. If the weight of the package is less than or equal to 0 pounds, inform the user and exit the program. The shipping charges are:

Weight of Package	Shipping Charge
2 pounds or less	$1.25
Over 2 pounds but not more than 6 pounds	$2.50
Over 6 pounds but not more than 10 pounds	$3.90
Over 10 pounds	$4.40

Create constants for the cutoff values of 2.0, 6.0, and 10.0, the value of 0.0, and for the 4 shipping charges.

Example Run #1:
(bold type is what is entered by the user)

Enter the weight of the package: 2.0

The shipping charge is $x.xx.

Example Run #2:

Enter the weight of the package: 0
The weight of the package must be greater than 0.00.

Answer 1

#include<stdio.h>
#include <stdlib.h>
main()
{
   float Weight;
   const float a=0;
   const float b=2;                    
   const float c=6;
   const float d=10;
  
   printf("Enter the weight of the package:");
   scanf("%f",&Weight);         //Taking weight of package as input from user
   if(Weight<a)
   {
   printf("The weight of the package must be greater than 0.00.");
   exit(0);
   }
   else if(Weight<=b)
   {
       printf("The shipping charge is:$1.25");
   }
   else if(Weight>b&&Weight<=c)
   {
   printf("The shipping charge is:$2.50");
   }
   else if(Weight>c&&Weight<=d)
   {
   printf("The shipping charge is:$3.90");
   }
   else
   {
   printf("The shipping charge is: $4.40 ");
   }
  
}
