How can I prevent dangling pointers in my code?

How can I prevent dangling pointers in my code?

To prevent dangling pointers, always set pointers to null after freeing the memory they point to.

Are there any specific coding practices I should follow?

Yes, use smart pointers in C++ or reference counting in languages like Swift to manage memory automatically.

What are the common causes of dangling pointers?

Common causes include deleting an object while still having pointers to it, or returning a pointer to a local variable.

Can you give an example of a dangling pointer?

Sure! If you have a pointer to a dynamically allocated array and you delete it without nullifying the pointer, that's a dangling pointer.
