hay guyz.

Anyways, I new to programming, I need to know how to use the || operator properly.

ie.

if number is not 3 or 4. ask for another input.
could someone give me an example?
not sure at what point in a loop it goes at.
assuming it could be in a do ( cout << "plz enter valid number: " cin >> number ) while (number != 3 || 4) or something?
but that doesn't work.
It keeps telling me that my number is invalid.

Cheers,
anon.

!!!(~n == ~(((!3)<<1)|1) || n == 4)

When your alternatives are in a continuous range, it's easier to do it like this:

while (3 <= number <= 4)

It's also more scalable as you don't have to add more code even if the range was 100 numbers long.

SEPPLES ? !

>>3 That makes some sense, but what happens when it's numbers like 4 and 6, without 5?
ie. input must be either 4 or 6. if you enter any other number, it should show an invalid message.

Then use ||. It's just like in logic, but I believe it short circuit evaluates. So something like if (1 || imUsingSepples()) {} would never evaluate imUsingSepples(). Any side effects of that function (dick in your ass, &c.) will not occur.

And || is a connective, not a predicate. You can only use it on true/false values. if (number = 3 || number = 4) {}

If you want to make several comparisons against the same integer, use a switch.
[code]switch (number) {
case 4:
case 6:
    cout << "Good job, faggot.";
    break;
default:
   cout << "Ur a faggot.";
}

Teaching him how to use Sepples is hardly helping. It's like giving someone AIDS of the brain.

a <= b <= c is always true if c >= 1, faggot.

>>9 Sepples is bad?
I not tried lisp, because I'm not expert enough.
I'll try sometime.

C++ seems to be easiest to pick up for now.
