When c like languages say so
$a = 5; $b = 1; $result = $a---$b; echo $a; #=>4 echo $b; #=>1 echo $result; #=>4
public class FunMaths{ public static void main(String[] args) { int result; int a = 5, b = 1; result = a---b; System.out.println(a); System.out.println(b); System.out.println(result); } }

The trick here is that it is doing either a prefix or postfix decrement (I guess it would depend on the compiler).
In the case of php and java, it does a postfix decrement, then it ignores the -1 on the end, resulting in {4, 1, 4}

I don’t think I’m getting the joke…have you overloaded the – operator?
triple – operators doesn’t have a valid meaning I’m aware of in C, at least. One is minus, two is decrement.
