Please move this somewhere, because Im not sure where to put it, this is for school btw.

Okay so who knows C? I need help on some modulus stuff, the code needs to detect if x is even, odd, and if it’s either, it also needs to check if its divisible by 3. This should work for any value of x. I have the even/odd detection so far:

```auto
int x = 5;
void main ()
{
    while (x > 0)
      {
        if (x%2 == 0)
          {
            printf("x is %d: even
", x);            
        } else  
          {          
            printf("x is %d: odd
", x);              
        }
        x--;
    }
}

```

Thanks for any help. AS people might get this too!
