Question

IN C++ PROGRAMMING

(We use #include <iostream>

and cout and cin)

Shipping Calculator

Speedy Shipping Company will ship your package based on the weight and how far you are sending the package, which can be anywhere in the world. They will only ship small packages up to 10 pounds. You need to have a program, which will help you determine how much they will charge.

The charges are based on each 500 miles shipped. The mileage should be in whole numbers. They are not prorated, i.e., 600 miles is the same charge as 900 miles; in other words, 600 and 900 miles is counted as 2 segments of 500 miles each.

Here is the table they gave you:

Package Weight Rate per 500 miles shipped	Charge
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

Your code needs to validate the input completely, e.g., the weight and mile amounts must be positive. If an input is invalid, e.g., the weight is zero or less, you should display an appropriate, professional error message, e.g., Error: Weight must be greater than zero!, which should be offset and surrounded by white space, so it stands out, and repeat getting that input until valid input is received. Keep in mind, the user will find it annoying if they must enter both the miles and weight at the same time, and only one of them caused an error, or they must reenter already valid data. Also, make sure you follow the Code Conventions and good programming practices, e.g., appropriately initialize variables to zeros, avoid stacked if or if-else constructs unless necessary, don’t use break or continue to get out of a loop, goto, etc.; in other words, you should NOT used stacked if/if-else constructs, break, or continue for this assignment.

At this point for the code, you should only solve the problem using what you learned from modules 1 – 5, i.e., NO arrays, functions other than main(), etc. Only if all the input is valid, should the program calculate and display one shipping charge, and pause, but not quit, before proceeding to a new customer. Your test cases should test the various possibilities, and the limits of the program, which means, you will need to use an appropriate loop, which will ask if you would like to process the next customer or not by asking them to enter an appropriate value. Once there are no more customers to process, the program should display Good-bye! and end. Remember to solve each aspect of the program separately, and then, put the parts together.

Hints: You may need to reset any values after you display the answer and before you get the input for the next customer. Big Helpful Hint: For the number of segments calculation, you may want to start with integer division, e.g., 1200 miles / 500 miles per segment = 2 segments, and then, expand on that.

You should be able to solve this problem with only one loop.

Answer 1

Hey,Hey,Hey!!!!

Fasten your seat-belt!!!

I like to explain and express things in such a manner so that everybody can easily understand.

So, let’s dive deep into our solution:-

Here is the Program Code:-

OUTPUT:-

If you need the code,here it is:-

#include<iostream>
using namespace std;

int main(){

   int choice;
   int miles,segment;
   double weight,charges,cost;

do
{
cout<<"Enter number of miles as whole number: ";
cin>>miles;
if(miles==0){
   cout<<"Error: Miles must be greater than zero!"<<endl;
   cout<<"Enter number of miles as whole number: ";

   cin>>miles;
}
cout<<"Enter the weight of the package in pounds: ";
cin>>weight;
if(weight==0){
   cout<<"Error: Weight must be greater than zero!"<<endl;
   cout<<"Enter the weight of the package in pounds: ";
   cin>>weight;
}
if(weight>10){
   cout<<"Error: We don't ship packages over 10 pounds!"<<endl;
   cout<<"Enter the weight of the package in pounds: ";
   cin>>weight;
}
segment=miles/500;
if(miles%500 != 0){
segment=segment+1;
}

if(weight<=2){
   charges=1.50;
}
if(weight>2 && weight<=6){
   charges=3.70;
}
if(weight>6 && weight<=10){
   charges=5.25;
}
cost=charges*segment;
cout<<"The cost to ship your package is: $"<<cost<<endl;
cout<<"Enter 1 to continue or 0 to quit: ";
cin>>choice;
}while (choice!=0);
cout<<"Good-Bye!";

return 0;
}

Please give it a thumbs up,if you liked the answer.
