How can I debug C++ errors effectively?

I'm getting a segmentation fault in my C++ program. How can I debug it?

A segmentation fault usually occurs when your program tries to access memory that it's not allowed to. You can start by checking pointers and array bounds.

I've checked my pointers, but I still can't find the issue. Any tools you recommend?

You can use tools like gdb (GNU Debugger) to step through your code and find where the fault occurs. Valgrind is also great for detecting memory leaks.

How do I use gdb to find the source of the segmentation fault?

To use gdb, compile your program with the -g flag to include debugging information. Then run gdb ./your_program, and use the run command to start it. When it crashes, use backtrace to see the call stack.

Thanks! What about fixing memory leaks?

For memory leaks, Valgrind is very effective. Run your program with valgrind --leak-check=full ./your_program to identify where memory is not being freed.
