Question

Programming 3: Multi-Way Branching

Shipping Charges

The Fast Freight Shipping Company charges the following rates:

• Given the Weight of Package (in Kilograms), use the following Rate ($) per 500 Miles Shipped.

• 2 kg or less = $1.10 per 500 Miles Shipped

• Over 2 kg but not more than 6 kg = $2.20 per 500 Miles Shipped

• Over 6 kg but not more than 10 kg = $3.70 per 500 Miles Shipped

• Over 10 kg but not more than 20 kg = $4.80 per 500 Miles Shipped

Write a program that reads the weight of the package and the distance it is to be shipped, and then displays the charges to two decimal points.

• Input Validation:
• Do not accept values of 0 or less for the weight of the package.
  • Print "ILLEGAL WEIGHT: BELOW MINIMUM"
• Do not accept weights of more than 20 kg (this is the maximum weight the company will ship).
  • Print "ILLEGAL WEIGHT: ABOVE MAXIMUM"
• Do not accept distances of less than 10 miles or more than 3,000 miles. These are the company’s minimum and maximum shipping distances.
  • Print "ILLEGAL DISTANCE"

I got stuck here:

#include
using namespace std;

int main(){
int i=0,miles;
   double j,weight,cost,distance;

   cin>>weight;
      if(weight<=0){
         cout<< "ILLEGAL WEIGHT: BELOW MINIMUM" << endl;
      }
      else(weight>20){
         cout<< "ILLEGAL WEIGHT: ABOVE MAXIMUM" << endl;
      }
       

   cin>>distance;
      while(distance<10 || distance >3000){
         cout<< "ILLEGAL DISTANCE" << endl;
      }
   i=miles/500;
   j=miles%500;

   if(j>0){
       i=i+1;
   }
   if(weight<=2){
       cost=i*1.10;
   }
   else if(weight>2 && weight<=6){
       cost=i*2.20;
   }
   else if(weight>6 && weight<=10){
       cost=i*3.70;
   }
   else if(weight>10 && weight<=20){
       cost=i*4.80;
   }
   cout<<"Cost of Shipping: " << cost;
   return 0;
}

Random inputs are....

Input : -1 2000

Expected inputs are : ILLEGAL WEIGHT: BELOW MINIMUM

Input: 1 5000

Expected output : ILLEGAL DISTANCE

input: 2 2000

Expected output : 4.40 (<--| enter symbol)

Please revise and let me know what i did wrong.....

Answer 1

Corrected Program

#include<iostream>
#include<iomanip>
using namespace std;

int main(){
    int i=0;
    double j,weight,cost,distance;

    cin>>weight;
      if(weight<=0)
      {
          cout<< "ILLEGAL WEIGHT: BELOW MINIMUM" << endl;
          return 0;
       }
       if(weight>20){
          cout<< "ILLEGAL WEIGHT: ABOVE MAXIMUM" << endl;
          return 0;
       }
    cin>>distance;
       if((distance<10 )||(distance >3000))
    {
          cout<< "ILLEGAL DISTANCE" << endl;
          return 0;
    }
    i=distance/500;
    j=int(distance)%500;

    if(j>0)
    {
        i=i+1;
    }
    i=float(i);
    if(weight<=2){
        cost=i*1.10;
    }
    else if((weight>2) && (weight<=6))
        {

    cost=i*2.20;

    }
    else if((weight>6 )&& (weight<=10)){
        cost=i*3.70;
    }

    else if((weight>10 )&& (weight<=20)){
        cost=i*4.80;
    }
    cout<<"Cost of Shipping: " <<setprecision(2)<< cost;
    return 0;
}
