How to print 1 to 100 without any looping using C#

Question

I am trying to print numbers from 1 to 100 without using loops, using C#. Any clues?

Answer 1

No loops, no conditionals, and no hardcoded literal output, aka "divide and conquer FTW" solution:

class P
{
    static int n;

    static void P1() { System.Console.WriteLine(++n); }

    static void P2() { P1(); P1(); }

    static void P4() { P2(); P2(); }

    static void P8() { P4(); P4(); }

    static void P16() { P8(); P8(); }

    static void P32() { P16(); P16(); }

    static void P64() { P32(); P32(); }

    static void Main() { P64(); P32(); P4(); }
}

Alternative approach:

using System;

class C
{
    static int n;

    static void P() { Console.WriteLine(++n); }

    static void X2(Action a) { a(); a(); }

    static void X5(Action a) { X2(a); X2(a); a(); }

    static void Main() { X2(() => X5(() => X2(() => X5(P)))); }
}

One more:

Console.WriteLine(
   String.Join(
      ", ", 
      Array.ConvertAll<int, string>(
         Enumerable.Range(1, 100).ToArray(), 
         i => i.ToString()
      )
   )
);

Answer 3

class Program
{
    static int temp = 0;

    public static int a()
    {
        temp = temp + 1;

        if (temp == 100)
        {
            Console.WriteLine(temp);
            return 0;
        }

        else
            Console.WriteLine(temp);

        Program.a();
        return 0;
    }

    public static void Main()
    {
        Program.a();
        Console.ReadLine();
    }
}

Answer 4

public void Main()
{
  printNumber(1);
}

private void printNumber(int x)
{
  Console.WriteLine(x.ToString());
  if(x<101)
  {
    x+=1;
    printNumber(x);
  }
}

Answer 5

This is more or less pseudo code I havent done c# in years, PS running on 1 hour of sleep so i might be wrong.

int i = 0;

public void printNum(j){       
    if(j > 100){
        break;
    } else {
        print(j);
        printNum(j + 1);
    }
}
public void main(){
    print(i);
    printNum(i + 1);       
}

Answer 6

static void Main(string[] args)
        {

            print(0);
        }

        public static void print(int i)
        {
            if (i >= 0 && i<=10)
            {

                i = i + 1;
                Console.WriteLine(i + " ");
                print(i);
            }
}
