What's the difference between != and =!?

[McBugzz]

I saw some C++ code that looked like that:

fullscreen =! fullscreen;

What's that =! thing? What does this statement mean?

 

[JOLESEN]

It means fullscreen is equal to NOT fullscreen.
i.e. an assignment.

Yes. It's less confusing if written like:

fullscreen = !fullscreen;

 

[Rhoon]

!= ... Not Equal To (Test condition)

Ie: if ( a != b) {}

=! ... Assignment to the not of the operand on the right.

Ie: if ( a =! b) {} .. If a = !b is assigned without error then the if statement is executed.
