Why can't you run code. This is obviously an exercise question - but it seems odd that you wouldn't run the code.

That's nice and all, but next time, don't do the OP's homework for them. It really doesn't help them think about the problem.

Nothing would be printed.
Your code wouldn't even compile.

C#

for (int i=20; i>0; i = i-2)
{
   Console.WriteLine(i)
}

A semicolon is missing at the end of line 3.
If you corrected this error like this:

C#

for (int i=20; i>0; i = i-2)
{
   Console.WriteLine(i);
}

then you would get the result as described in solution 1.
