No. it's not required

The C++ language guarantees that delete p will do nothing if p is equivalent to NULL. As you might get the test backwards, and as most testing methodologies force you for performs test explicitly every branch point, you should not put in the redundant if test.

Wrong:                    

if (p != NULL)

delete p; Right: delete p;
