🚌 BusFlow – Console Based Bus Reservation System (C)

BusFlow is a console-based Bus Ticket Reservation System built using the C programming language.

This is my first complete system-level project in C where I implemented real-world concepts like seat management, ticket generation, waiting list handling, cancellation, and file persistence.

🚀 Project Features

🔎 1. Bus Search System

✔ Search bus by:

• Source
• Destination
• Date

✔ Case-insensitive search

---

💺 2. Smart Seat Allocation System

Two booking modes:

🔹 Auto Mode

Seats are automatically assigned based on passenger priority:

Category	Seat Range
Disabled	1 – 2
Emergency	3 – 4
Pregnant	5 – 6
Senior Citizen (60+)	7 – 8
Normal	9+

🔹 Manual Mode

• User selects seat manually
• System validates:
  • Seat availability
  • Seat priority eligibility
  • Input correctness

---

🎟 3. Unique Ticket ID Generation

• Automatically generates incremental Ticket IDs
• Stored in ticketid.txt
• Starts from 1000
• Persists between runs

---

💾 4. File Handling (Data Persistence)

The system saves data even after program closes.

Files used:

• seats.dat → Stores seat booking status
• tickets.txt → Stores confirmed ticket records
• ticketid.txt → Stores last generated ticket ID

---

⏳ 5. Waiting List System

If seats are full:

• Passengers are moved to waiting list

On cancellation:

• Seats are reallocated based on priority

---

❌ 6. Ticket Cancellation

• Cancel using Ticket ID
• Frees allocated seats
• Automatically reassigns seat to waiting list passenger

---

---

🛠 Concepts Used

• Structures (struct Bus, struct Passenger)
• Arrays
• Global variables
• File handling (fopen, fread, fwrite, fprintf)
• Binary file storage
• String manipulation
• Case-insensitive search
• Input validation
• Modular programming
• Priority-based logic design

▶️ How to Run the Program

Step 1: Compile

gcc Module1.c -o BusFlow

Step 2: Run

./BusFlow

🧠 System Workflow

1. Initialize buses
2. Load saved seat data
3. Display available buses
4. Search bus
5. Enter passenger details
6. Choose seat mode (Auto / Manual)
7. Generate temporary ticket
8. Confirm booking
9. Save ticket & seat data
10. Allow cancellation if needed

🎯 Learning Outcomes

Through this project, I learned:

• How real-world reservation systems work
• How to persist data using files
• How to design priority-based seat logic
• How to manage waiting lists
• How to handle user input safely
• How to modularize large C programs

📌 Future Improvements

• Multiple ticket lookup
• Admin dashboard
• Payment simulation
• Multiple bus management via file
• Database integration (MySQL)
• Better UI formatting
