School asssignment with loop and if help

-----------------------------------

var Number : int
loop
    put "Please enter a number from 1 - 10 (enter -1 to exit)"
    get Number
exit when Number = -1    
if Number not= 3
            or
            Number not= 5
            or
            Number not= 7
            or
            Number not= 9
            or
            Number not= 1
            then
        put "Number is even"
        
        elsif Number not= 2
                or
                Number not= 4
                or
                Number not= 6
                or
                Number not= 8
                or
                Number not= 10
                then
            put "Number is odd"
        end if
end if
    end loop

i need help with this because its probably something really obvious im missing.. btw what this is supposed to do is its supposed to ask you for a number input from 1-10 and its supposed to tell you if number is odd or even and when you enter -1 it exits program

the or's should be and instead, and you have an extra end if

ALTHOUGH this can be done way easier
and hint is the % (mod) sign, and even number are the numbers that are divisible by _

something obvious is extra. You have one if statement, but two "end if" lines.

Also, if number is not odd, you know that it's even -- you don't have to check it the second time.

And there's a simple way to check if any number is even or odd, just divide by 2 and check what the remainder is.

Edit: heh, HeavenAgain keeps on replying just slightly faster than me... again!

Ignore this post, I see that you are already using the modulus operator.

I suggest search proper formats for find odd and even..

Hint: Search div under F10

Hint: Search div under F10
I think you mean mod. Which already has been mentioned 3 times in this thread.

var num : int
get num

if num mod 2 = 0 then
put "That number is even"
end if

That should help.

That's my favorite thing about programming, you learn something simple in the beginning, and do some long, repetitive work to make a program run. Then you learn a something new, and you bring your code from 500 lines to 100. Efficiency is fun!

puts "That number is #{(gets.to_i % 2 == 0) ? "even" : "odd"}"

:lol:
