    Unhappy I have a newbie question...:/

    Okay, so I've been learning C++. I got to the second page in the tutorials, and can make my computer say stuff. I can even talk back to it. But, then I got to booleans and got stuck. I understand the <, >, ==, all of that stuff, but evaluating gets me completly puzzled.

    !( 1 || 0 )

    That's what I'm talking about. It says to evaluate it. I understand that ! means NOT and stuff, but how to I get it down to 1 or 0?

    Thanks SO much.

    It's just like regular arithmetic, except with 1 and 0 instead of real numbers.

    || is like addition, && is like multiplication, and not does not have a direct analogue.

    So just as you would simplify 7+3*5 to 7+15 and then to 22, so you would simplify !(1||0) to !(1) and then to 0.
    It is too clear and so it is hard to see.
    A dunce once searched for fire with a lighted lantern.
    Had he known what fire was,
    He could have cooked his rice much sooner.

    OH! It makes so much sense now! Thanks
