How do I debug a segmentation fault in my C++ program?

Debugging a segmentation fault can be tricky. First, ensure you're using a debugger like gdb. Have you tried running your program with it?

No, I haven't used gdb before. How do I start?

You can start gdb by running gdb ./your_program_name in your terminal. Then, use the run command to execute your program.

What should I do if it crashes?

If it crashes, gdb will show you where it happened. You can use the backtrace command to see the call stack and identify the source of the fault.

Thanks! Any tips on common causes of segmentation faults?

Common causes include dereferencing null pointers, accessing out-of-bounds array elements, and using uninitialized variables. Always check these areas!
