Using ||

How would I write that to make it work?

while (choice !=(0)||(1)||(2)||(3)) {cout<< "Try again "; cin>> choice;}

((choice!=0) && (choice!=1)&&(choice!=2)&&(choice!=3))

Z.

why not
choice>3||choice<0

Do I have to rewrite choice every time? Is there any way around doing that?

And I didn't want to use the < > becuase that does not work for characters.

You have to rewrite choice each time.

And < > both work with characters.

Do you mean that C++ follows the alphabet?

C++ knows that 'A' comes before 'B', if that is what you are asking.

Z.

But 'a' comes after 'Z', so it doesn't work every time.

Great! Thank you.

But of course... 'Z' is a much better letter :D

assuming choice is an alpha you could flag off the lower case bit
choice&0xdf<'C'

Hehe, sure.. You can also do choice &= 3; in the original question and then not worry about an invalid choice ;)

hehe how about this for the test ;)
choice&0xFFFFFFFC
