,Question 1 Peter wants to send a box containing a painting to
London. The Post Office sends parcels to London via GlobalMail or
DHL. If GlobalMail is chosen, the cost is R108 per kg if the parcel
goes to zone 1 to 3 in London, and R130 per kg if the parcel goes to
zone 4 to 6. If DHL is chosen, the actual weight is compared to the
volumetric weight, and whichever is the higher weight, is used in
the calculation. The volumetric weight is calculated by the formula
(length * width * height) / 5000, where length, width and height is
the size of the box in cm. The cost per kg for DHL is R70. Write a
program that will calculate the price to be paid for sending a parcel
to London. The program must use two overloaded functions, each
named calcPostage. The user must be asked if he wants to use
GlobalMail or DHL. Define a char variable and ask the user to input
„d‟ for DHL or „g‟ for GlobalMail. If he chooses GlobalMail, the
zone must be requested. The program must validate that the zone is
between 1 and 6. If he chooses DHL, the length, width and height of
the box must be requested. The first function will receive two
parameters, one of type double representing the weight of the parcel,
and one of type int, representing the zone. The second function will
receive four parameters of type double, representing the actual
weight, and the length, width and height of the box in cms. The
second function will first determine whether the actual weight or the
volumetric weight is the highest, before calculating the cost. Both
functions will return the cost in a variable of type double. The main
function should then display the total cost. Define const variables
where applicable. 3
, Here's a C++ program that implements the described functionality
for calculating the cost of sending a parcel to London using either
GlobalMail or DHL:
cpp
Copy code
#include <iostream>
#include <cmath> // for ceil function
using namespace std;
// Constants for GlobalMail rates
const double GM_ZONE1_3_RATE = 108.0; // Rands per kg for
zones 1 to 3
const double GM_ZONE4_6_RATE = 130.0; // Rands per kg for
zones 4 to 6
// Constant for DHL rate
const double DHL_RATE_PER_KG = 70.0; // Rands per kg for
DHL
// Function prototypes
double calcPostage(double weight, int zone);
double calcPostage(double actualWeight, double length, double
width, double height);
int main() {
char choice;
double weight, length, width, height, cost;
int zone;
// Ask user for choice of mail service
cout << "Enter 'g' for GlobalMail or 'd' for DHL: ";
