Question

We are given the following code and must modify it. The following are the instructions, and below the instructions is the code.

// This menu-driven Health Club membership program carries out the
// appropriate actions based on the menu choice entered. A do-while loop
// allows the program to repeat until the user selects menu choice 4.

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

// Constants for membership rates
const double ADULT_RATE = 40.0;
const double CHILD_RATE = 20.0;
const double SENIOR_RATE = 30.0;

void displayMenu();   
void verifyChoice(int &);
void processChoice(int &);

int main()
{
   int choice; // Menu choice
  
do
{
displayMenu();
   cin >> choice;
verifyChoice(choice);
   processChoice(choice);
      
} while (choice != 4); // Loop again if the user did not
system("pause"); // select choice 4 to quit
return 0;
}
void displayMenu(){
// Display the menu and get the user's choice
cout << " Health Club Membership Menu ";
cout << "1. Standard Adult Membership ";
cout << "2. Child Membership ";
   cout << "3. Senior Citizen Membership ";
   cout << "4. Quit the Program ";
   cout << "Enter your choice: ";
}
void verifyChoice(int &choice)
{
// Validate the menu selection
   while ((choice < 1) || (choice > 4))
       {
       cout << "Please enter 1, 2, 3, or 4: ";
           cin >> choice;
       }
}
void processChoice(int &choice)
{
int months; // Number of months
double charges; // Monthly charges
// Process the user's choice
   if (choice != 4)
   {   cout << "For how many months? ";
       cin >> months;
      
       // Compute charges based on user input
       switch (choice)
       {
case 1: charges = months * ADULT_RATE;
break;
case 2: charges = months * CHILD_RATE;
break;
case 3: charges = months * SENIOR_RATE;
      }
      // Display the monthly charges
      cout << fixed << showpoint << setprecision(2);
      cout << "The total charges are $" << charges << endl;
   }
}
