[QUOTE="A, post: 4069736"] Here is one example where setting to null would have some use although I would say this is a bad practice and not very clean code - it can be probably restructured to be much cleaner: int *a = new Object(); a->DoStuff(); if (some event) { delete a; a = null; } // do something else if (a != null) { // code if object is still defined a->DoMoreStuff(); } else { // code if object is undefined, print error or whatever } [/QUOTE]
