NULL

[dalawh]

Can someone make a list telling me how something is indicated as NULL? Like what uses 0 as NULL, etc.

[Moschops]

A null pointer is indicated with either NULL or 0.

In C++ 11, there's now also the nullptr keyword

[dalawh]

They all don't use 0, do they? Like array, pointers, etc.

[Moschops]

Only a pointer can be null. You want an int to be null? It can't be. Only pointers.

[dalawh]

Oh okay. But I thought arrays can be null because when you first create them and when you don't put values into them, aren't they null?

[Ortonas]

No, it will contain random values.

[dalawh]

Okay. Thanks for the replies.
