Hi
I don't understand why the result of this code is "3 is a prime number".
Variabel i in the for ... start at 3/2 = 1 (because of int). So according to me, the loop should never be executed because the condition is i > 1 and this is never satisfied.. But, as i said, this code gives "3 is a prime number" (and of course that's right).
Same with value x= 2 ("2 is not a prime number").
Thanks.
static void Main(string[] args)
{
int x = 3;
string f = "";
for (int i = x / 2; i > 1; i--)
{
if (x % i == 0)
{
f = "not a";
break;
}
else
f = "a";
}
Console.WriteLine("{0} is " + f + " prime number", x);
}
