Program 5: Shipping Calculator

The Speedy Shipping Company will ship packages based on how much they weigh and how far they are being sent. They will only ship small packages up to 10 pounds. You have been tasked with writing a program that will help Speedy Shipping determine how much to charge per delivery.

The charges are based on each 500 miles shipped. Shipping charges are not pro-rated; i.e., 600 miles is the same charge as 900 miles; i.e., 600 miles is counted as 2 segments of 500 miles.

Here is the table they gave you:

Package Weight                                           Rate per 500 miles shipped

2 pounds or less $1.50

More than 2 but not more than 6                              $3.70

More than 6 but not more than 10                            $5.25

Test Case 1:

Input Data:

Weight:            1.5 pounds

Miles:              200 miles                                (This is one 500-mile segment.)

Expected result:

To ship a 1.5 pound package 200 miles, your shipping charge is $1.50.

Test Case 2:

Input Data:

Weight:            5.6 pounds

Miles:              1200 miles                              (This is three 500-mile segments.)

Expected result:

To ship a 5.6 pound package 1200 miles, your shipping charge is $11.10.

Test Case 3:

Weight:            1.0 pounds

Miles:              2000 miles                               (This is four 500-mile segments.)

Expected result:

To ship a 1.0 pound package 2000 miles, your shipping charge is $6.00.

Test Case 4:

Weight:            8.5 pounds

Miles:              12345 miles                            (This is twenty-five 500-mile segments.)

Expected result:

To ship a 8.5 pound package 12345 miles, your shipping charge is $131.25.

Test Case 5:

Weight:            12.8 pounds

Miles:              345 miles  

Expected result:

Sorry, we only ship packages of 10 pounds or less.

Hints: This program does not need any loops. The program will calculate one shipping charge and stop. Your test cases should test the various possibilities, and the limits of the program.

BIG Helpful Hint: You can use integer division. For example: 1200 / 500 = 2

Answer 1

C Code:

#include<stdio.h>

int main() {
float weight = 0, rate =0, total = 0;
int miles =0, ship =0;
//Getting the inputs from user
printf("Enter weight of package: ");
scanf("%f", &weight);
printf("Enter shipping distance: ");
scanf("%d", &miles);
//Calculating the rate as per weight
if(weight >=0 && weight<=10){
if(weight <=2){
rate = 1.5;
}
else if(weight >2 && weight<=6){
rate = 3.7;
}
else{
rate = 5.25;
}
ship = (miles/500) +1;
total = rate * ship;
//printing out the result
printf("To ship a %.1f pound package %d miles, your shipping charge is $%.2f.",weight, miles, total);
}
else{
printf("Sorry, we only ship packages of 10 pounds or less");
}
}
