Issues are null at this time

Null Eins Zwie Drei 0123

ex.1:
<faceprint> we returned js->roomlist without setting it, so it was NULL

ex.2:
(In C++:
void function()
{
int variable;
}

'variable' would have a value of NULL until it is initialized, and 'function' would return NULL because it was created with a 'void' data type.)

ex.3:
"Your sister is soooo stupid, it's like she's NULL between the ears..."

Pressing return on an empty web form returns null values.

1. My bedroom is just null.
2. The command prompt asked me to type my name. I hit 'Enter' without typing a name, and on the webpage, it said 'Hello, null! Welcome to my site!'

Who is that?
Oh that's Null, he's a legend.
