Dangling pointer points address of freed memory?

Question

Then what way we can use dangling pointer?

Answer 1

U can assign new address to reuse the same pointer variable, instead of declaring a new pointer variable if you need.
Hope this helps...!!!

Answer 2

A good practice I use it to set the dangling pointer to null after I free the memory. You can always set it to a different memory address like Kuri said too.
