ARRAYS

[Neo]

If I had an array with 121 variables of boolean, how would I check to
see if all of them are true?

like this but shortened
if num(1)=true and num(2)=true and num(3)=true...etc

Use a loop. Remember that checking to see if they're all true is the same as checking to see if any of them are false.

code:

var allTrue : boolean := true for x: 1..121 if num(x) = false then allTrue := false exit end if end for

Close, but you don't need the variable. And as long as you posted code...

code:

function allTrue (arr : array 1 .. * of boolean) : boolean    for i : 1 .. upper (arr)       if not arr (i) then          result false       end if    end for    result true end allTrue

I stand corrected.

You had the basic idea down fine. You just weren't taking full advantage of "result".
