Self-Writer: Coding Challenge
Ed Sullivan's coding challenge
In his new book, Under Pressure and On Time, Ed Sullivan reports that NuMega had a standard coding test for applicants:
For years, we gave the same programming test to every developer. It was a straightforward test that required no setup or external knowledge from manuals. The candidates were asked to write a program that could print its source to the screen exactly, without performing any file input.
Well, I've done this before, but it was a long time ago, so why don't we give this a whirl?

Here is the best solution I could come up with in C#:
using System;
public class Class1
{
static void Main(string[] args)
{
Console.Write(code + '\u0022' + code + '\u0022' + ';' + '\n' + '}');
}
public static string code =
@"using System;
public class Class1
{
static void Main(string[] args)
{
Console.Write(code + '\u0022' + code + '\u0022' + ';' + '\n' + '}');
}
public static string code =
@";
}
[Incase anyone is interested I colorized this code using CodeHtmler, written by Shawn Van Ness and Wes Haggard]
Update: I saw something that wanted me to see what the shortest possible "quine" I could come up with in C#. I came up with one that is 188 chars (including spaces)
class
c{static void Main(){System.Console.Write(d+'\x22'+d+'\x22'+';'+'}');}static string d="class c{static void Main(){System.Console.Write(d+'\x22'+d+'\x22'+';'+'}');}static string d=";}
