, 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 fulfills the requirements specified:
cpp
Copy code
#include <iostream>
using namespace std;
// Constants for GlobalMail costs
const double GM_ZONE_1_3_COST_PER_KG = 108.0;
const double GM_ZONE_4_6_COST_PER_KG = 130.0;
// Constant for DHL cost per kg
const double DHL_COST_PER_KG = 70.0;
// 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;
