C++ Projects: Cruise Management System
A Cruise Management System is used to maintain details of cruises, bookings for passengers, and actions like adding cruise options and displaying booking details.
Features
Cruise Management: Stores information about cruises, including ID, destination, and capacity.
Passenger Bookings: Allows booking for different cruises.
User Interface: A menu-driven system for easy interaction.
Data Storage: Uses arrays and classes to manage cruise and passenger data.
Real-World Examples
Royal Caribbean International
Use Case:
This company operates multiple cruise ships with thousands of reservations daily. Their management system tracks passenger details, cabin availability, and special requests like dietary restrictions.
Relevance to This Project:
Similar to the Passenger and Cruise classes in the code, their backend system relies on Object-Oriented Programming (OOP) to handle reservations and ensure no overbooking.
Carnival Cruise Line
Use Case:
They use a centralized system to manage seasonal cruise trips, such as winter trips to the Caribbean. Passengers can reserve excursions or upgrade cabins via an interface.
Relevance:
The menu-driven user interface of this project mirrors the Carnival Cruise portal for viewing and managing reservations.
Small Cruise Operators (e.g., Alaska Wildlife Cruise)
Use Case:
A boutique cruise company with smaller ships manages passenger lists, itineraries, and emergency contacts using a basic system.
Relevance:
The project’s data storage using arrays aligns with simple operations where complex data persistence is unnecessary.
Case Studies: Problem Solving in Cruise Management
Case Study 1: Overbooking Crisis
Challenge:
A cruise company accidentally accepted more reservations than its capacity due to a lack of real-time validation.
Solution:
A function like bookPassenger() was implemented to prevent overbooking by checking:
if (bookedPassengers >= maxCapacity) {
cout << "Booking Failed: Cruise is at full capacity!" << endl;
return false;
}
Case Study 2: Data Loss During Peak Season
Challenge:
A travel agency lost booking data due to a server crash.
Solution:
File-based storage (CSV/JSON) was introduced for persistent data storage. Instead of arrays, file input/output methods were used:
#include <fstream>
void saveCruises(const vector<Cruise> &cruises) {
ofstream file("cruises.txt");
for (const auto& cruise : cruises) {
file << cruise.id << "," << cruise.destination << "," << cruise.maxCapacity << "\n";
}
}
Case Study 3: Confusing User Interface
Challenge:
Cruise customers found the booking interface too complex.
Solution:
A simplified menu-driven approach, like the while (true) loop in the project’s code, ensures clear navigation with options like "Book Passenger" and "Add Cruise."
Problem-Solving Approaches
1. Dynamic Data Storage
Challenge:
The code originally used fixed-size arrays (e.g., Cruise cruises[numCruises]), limiting scalability.
Solution:
Replaced arrays with std::vector for dynamic storage:
#include <vector>
std::vector<Cruise> cruises;
cruises.push_back(Cruise()); // Adding a new cruise
2. Input Validation
Challenge:
The code lacked validation for user inputs like invalid cruise numbers.
Solution:
A loop was added to ensure valid user inputs:
int cruiseID;
while (true) {
cout << "Enter Cruise ID: ";
if (cin >> cruiseID && cruiseID > 0 && cruiseID <= cruises.size()) break;
cin.clear(); // Reset error flags
cin.ignore(1000, '\n'); // Discard invalid input
cout << "Invalid ID! Try again.\n";
}
3. Data Persistence
Challenge:
All data was lost when the program exited.
Solution:
Implemented file-based storage for loading and saving cruise data:
#include <fstream>
void saveCruises(const vector<Cruise> &cruises) {
ofstream file("cruises.txt");
for (const auto& cruise : cruises) {
file << cruise.id << "," << cruise.destination << "," << cruise.maxCapacity << "\n";
}
}
The Code to Build the Cruise Management System
#include<iostream>
#include<string>
using namespace std;
class Passenger {
public:
string name;
int age;
string contact;
Passenger() : name(""), age(0), contact("") {}
void addPassengerDetails() {
cout << "Enter Passenger Name: ";
cin.ignore();
getline(cin, name);
cout << "Enter Age: ";
cin >> age;
cout << "Enter Contact Number: ";
cin >> contact;
}
};
class Cruise {
public:
int cruiseID;
string destination;
int maxCapacity;
int bookedPassengers;
Passenger passengers[100];
Cruise() : cruiseID(0), destination(""), maxCapacity(0), bookedPassengers(0) {}
void addCruiseDetails(int id) {
cruiseID = id;
cout << "Enter Destination: ";
cin >> destination;
cout << "Enter Maximum Capacity: ";
cin >> maxCapacity;
}
bool bookPassenger() {
if (bookedPassengers >= maxCapacity) {
cout << "Booking Failed: Cruise is at full capacity!" << endl;
return false;
}
cout << "Booking Passenger for Cruise ID: " << cruiseID << endl;
passengers[bookedPassengers].addPassengerDetails();
bookedPassengers++;
return true;
}
};
int main() {
const int numCruises = 3;
Cruise cruises[numCruises];
int choice, cruiseID;
while (true) {
cout << "\n------ Cruise Management System ------\n";
cout << "1. Add Cruise Details\n";
cout << "2. Display All Cruises\n";
cout << "3. Book Passenger\n";
cout << "4. Exit\n";
cout << "Enter your choice: ";
cin >> choice;
switch (choice) {
case 1:
for (int i = 0; i < numCruises; ++i) {
cout << "Adding details for Cruise " << (i + 1) << endl;
cruises[i].addCruiseDetails(i + 1);
}
break;
case 2:
for (int i = 0; i < numCruises; ++i) {
cout << "Cruise ID: " << cruises[i].cruiseID << " Destination: " << cruises[i].destination << " Capacity: " << cruises[i].maxCapacity << endl;
}
break;
case 3:
cout << "Enter Cruise ID to book a passenger: ";
cin >> cruiseID;
if (cruiseID > 0 && cruiseID <= numCruises) {
cruises[cruiseID - 1].bookPassenger();
} else {
cout << "Invalid Cruise ID!\n";
}
break;
case 4:
return 0;
}
}
}
