Why the output of below c# program is 4 not 5?

Question

int x = 16;
int y = 3;
x %= y*2;
Console.WriteLine(x++);

Answer 1

third line: x = 16%6 = 4
fourth line: print x *and then* increment it by one

So in effect, x=4 is printed out and after that x=5 (but is no longer printed again)

Answer 2

the output is 4, but if you want to get 5 replace x++ with ++x.

Answer 3

Dang it @Kuba, you beat me to it! Good answer by the way!
