NULL check before deleting an object with an overloaded delete

Question

This came up as one of the code review comments.

Is it a good idea to check for NULL before calling delete for any object?

I do understand delete operator c

Answer 1

From Standard docs, 18.5.1.1.13 under delete,

Default behavior: If ptr is null, does nothing. Otherwise, reclaims the storage allocated by the earlier call to operator new.

So, you don't have to check by default..
