How can I debug runtime errors in C++?

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

Debugging runtime errors can be tricky. First, can you provide the error message you're seeing?

The error says 'Segmentation fault'. What does that mean?

A segmentation fault usually occurs when your program tries to access memory that it's not allowed to. This can happen due to dereferencing a null pointer or accessing an array out of bounds.

How can I find out where the error is happening?

You can use a debugger like gdb. Run your program with gdb, and when it crashes, you can use the 'backtrace' command to see the call stack.

What if I don't want to use a debugger?

You can add print statements to your code to trace the execution flow and identify where it crashes.
