Avoiding dangling pointers.

I read that you should assign null (0) to all pointers that you call
delete on.

Does that mean:

*p=0(set the value pointed to to 0).

or

p=0(set the address held to zero).

The last one is awkward for none would want a pointer pointing
to address zero(even though it compiles fine, you can´t assign
anything to it).

I find the first still awkward(though less than the seccond) for I
would assume you shouldn´t
assign values to places you no longer use.

Thanks,

Rafael
