Question
Please, do you mind modify this program and add the following features:
Add family membership for $60, Add the code to write new membership accounts to the file "members.txt", Add choice to the menu to view member accounts, "members.txt", Counts of each type of membership processed and display to the console at the end, quit and Tip - use an array of counters.
// 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;
}
}
