NULL pointer and deleting it

Question

Is there any reason to check for a NULL pointer before deleting ?

Is there a bug in this code

Type * p = 0;
delete p;

p is a null pointer here. will there be any issues in implementing this.

`delete` is not a part of C. It is C++. Tag "c" changed to "c++" — phoxis, Jun 18 '11 at 17:23

No, it's specified in the C++ specification that delete on a null pointer does nothing.

The OP has tagged the question [tag:c] not [tag:c++], but it still should be safe. – ChrisF Jun 18 '11 at 17:20

Well, I assumed that it was going about C++ because I saw delete, sorry. But I still think the OP meant C++. – orlp Jun 18 '11 at 17:22

_I KNOW_. That's why I think the OP meant C++ and not C. – orlp Jun 18 '11 at 17:23
Of course! It's been too long since I did any of this. Must remember to think before typing. – ChrisF Jun 18 '11 at 17:23
@nightcracker I was conforming what you said. – Iustin Jun 18 '11 at 17:26
