What are some common errors in pointer arithmetic?

Common errors in pointer arithmetic include dereferencing null pointers, incorrect pointer increments, and type mismatches.

Can you explain what happens when I dereference a null pointer?

Dereferencing a null pointer leads to undefined behavior, which can cause your program to crash or produce unexpected results.

How can I avoid these errors in my code?

To avoid errors, always initialize pointers, check for null before dereferencing, and ensure pointer arithmetic is done within bounds.

What tools can help me detect these errors?

You can use static analysis tools like Valgrind, AddressSanitizer, or compiler warnings to help detect pointer-related errors.
