I\'ll start out by saying, use smart pointers and you\'ll never have to worry about this.

What are the problems with the following code?

Answer 1

I can imagine setting a pointer to NULL after deleting it being useful in rare cases where there is a legitimate scenario of reusing it in a single function (or object). Otherwise it makes no sense - a pointer needs to point to something meaningful as long as it exists - period.
