🐞 Common Errors Faced During Development

Here are the realistic and commonly expected errors that occur while building a Bus Reservation System in C:

1️⃣ File Not Found (data.txt missing)

The program stores booking information inside data.txt. If the file is missing, the program cannot load or save data.

• Fix: Create an empty data.txt file in the project folder.

2️⃣ Wrong Input Crash (Letters instead of numbers)

When the program expects a number but the user enters text, it may crash.

• Fix: Validate numeric input and clear the buffer.

3️⃣ Seat Number Out of Range

If the user enters an invalid seat number (too high or low), the program may behave incorrectly.

• Fix: Add range checks to ensure the seat number is valid.

4️⃣ Compilation Errors (Missing function prototypes)

Errors appear when functions are used without being declared, or header file is not included properly.

• Fix: Ensure all function prototypes are included in bus.h.

5️⃣ Data Overwriting (Wrong file mode)

Using "w" instead of "a" overwrites previous booking data.

• Fix: Use "a" mode when adding new records.
