More Than Nothing

Someone linked to http://golf.shinh.org/p.rb?FizzBuzz today and I couldn’t help but have a go. Currently I’m ranked 20 in the C# solutions, but I just can’t seem to shave off those last few characters. [The following code is obviously unminified]

class X {
	static void Main() {
		for (int i=0; i<100;) {
			var z = ++i % 5 > 0 ? null : "Buzz";
			System.Console.WriteLine(i%3 > 0 ? z??i+"" : "Fizz" + z);
		}
	}
}

While googling around for inspiration on other possible angles to attack the problem I saw many so-called “good” and “simple” solutions, all of which looked far too complicated to me. So here’s what I think a good solution looks like.

using System;

static class FizzBuzz {
	static void Main() {
		for (int i = 1; i <= 100; i += 1) {
			var fizz = i % 3 == 0;
			var buzz = i % 5 == 0;

			if (fizz) {
				Console.Write("Fizz");
			}

			if (buzz) {
				Console.Write("Buzz");
			}

			if (!fizz && !buzz) {
				Console.Write(i);
			}

			Console.WriteLine();
		}
	}
}

It doesn't over-complicate things - there's no need to build up intermediate strings or to have nested branches - and it's quite clear from reading it what it does.

Now if I can just squeeze those last few characters out I can get to the top of the chart…
