Answer 1

Check it your self its your last if condition not true in any of the input check it your self

Answer 2

for (int n = 2;n <= x/2;x++) //here you x++,
{
if (x%n==0 && input/Math.Pow(n, 2)==0)

According to these conditions, when x=4, this loop starts.. 2<=4/2 is true, but input/4==0 false, next x=5, x%n==0 false,
x=6, loop condition 2<=6/2 false..
After x=8, all loops stop without any printing..

Answer 3

Because the conditions of the code never happen
