🚉 TRACK TRACER

Track Tracer is a robust server-side application designed to manage passenger details for a transportation system. It leverages socket programming to communicate with clients—typically passengers booking train seats—ensuring a smooth and secure booking process.

🛠️ Functionality

📡 Socket Creation and Configuration

• The server establishes a socket using socket(AF_INET, SOCK_STREAM, 0) for network communication.
• Configures the server address (struct sockaddr_in) to bind to a specific IP address and port.

🚀 Server Initialization

• Binds the socket to the specified IP address and port using bind().
• Listens for incoming connections using listen().

🤝 Accepting Client Connection

• Upon receiving a connection request (accept()), the server establishes a connection with the client.

📨 Sending Initial Welcome Message and OTP

• Sends a welcome message (server_message) to the client upon connection.
• Generates a random 4-digit OTP (otp) and sends it to the client for authentication.

🔑 Passkey Verification

• Prompts the client to enter a passkey.
• Compares the received passkey with the generated OTP.
• If the passkey matches, the server proceeds with collecting passenger details.

🧳 Collecting Passenger Details

• Requests and receives the passenger's name, age, gender, date of travel, preferred train choice, and seat preference from the client.

🎫 Updating Seat Matrix

• Receives the seat selection from the client and updates the seat matrix accordingly.

💾 Saving Passenger Information

• Saves the collected passenger details along with the seat allocation in a file named ticket.txt.

🍽️ Food Ordering

• Offers the client the option to order food during the journey.

⚠️ Error Handling

• Catches errors during socket operations and exits gracefully if any operation fails.

🎨 Colorful Console Output

• Utilizes ANSI color escape codes (defined as macros) to enhance console output with colors for better readability.

🚀 Usage

1. Compile and run the server program on a machine connected to a network:

   gcc server.c -o server

2. Run the compiled executable:

   ./server

3. Connect to the server using a compatible client-side application.

   • Follow the prompts to enter necessary details and complete the booking process.

📝 Notes

• Ensure the server is running and reachable from the client-side application.
• This program serves as a demonstration and requires further enhancements for robustness, security, and scalability in a real-world scenario.
