What are dangling pointers in C++?

How can I avoid creating dangling pointers?

To avoid dangling pointers, ensure that you set pointers to nullptr after deleting the memory they point to, and be cautious with object lifetimes.

Can you give me an example of a dangling pointer?

What are the consequences of using dangling pointers?

Using dangling pointers can lead to undefined behavior, crashes, or data corruption, as they may point to invalid memory.
