This works for both positive and negative numbers:
privatestatic bool isEven(int number)
{
bool result = true;
while (number < 0)
{
number = number - 1;
if (result == true)
result = false;
else
result = true;
}
while (number > 0)
{
number = number - 1;
if (result == true)
result = false;
else
result = true;
}
return result;
}
This works for both positive and negative numbers:
private static bool isEven(int number) { bool result = true; while (number < 0) { number = number - 1; if (result == true) result = false; else result = true; } while (number > 0) { number = number - 1; if (result == true) result = false; else result = true; } return result; }Output:
isEven(4) = True isEven(5) = False isEven(-4) = True isEven(-5) = False
