Using ||
How would I write that to make it work?
while (choice !=(0)||(1)||(2)||(3)) {cout<< "Try again "; cin>> choice;}

why not
choice>3||choice<0

writing software in C++ is like driving rivets into steel beam with a toothpick.
writing haskell makes your life easier:
reverse (p (6*9)) where p x|x==0=""|True=chr (48+z): p y where (y,z)=divMod x 13

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.

Do you mean that C++ follows the alphabet?

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

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

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
