Challenge: Write a program that never stops

#discuss #java #python #javascript

Write an endless loop, write some confusing gotos...

The rules are simple: Write a program that never stops. Language: Any. Try to keep it short and confusing :D

Here is an example:

for(i=0; i<10; i++){
    for(j=0; i<10; j++){
        System.out.println("Blubb.");
    }
}

Post your funny, creative solutions below.

class Program
{
   public static IEnumerable<string> HelloWorld()
   {
      while(true) yield return „Hello World“;
   }
   public static void Main(string[] args)
   {
      foreach (string  s in HelloWorld())
      {
         Console.WriteLine(s);
         Thread.Sleep(1000);
      }
   }
}

#!/usr/bin/env perl

$SIG{INT} = 'IGNORE';

while ( 1 ) {
  print "stop me if you can\n";
  sleep 1;
}

# Pretty standard but I went a bit further and made it ignore CTRL-C as well, so you have to `kill -9` it :)

The original post was tagged with javascript and dev.to has a bias toward javascript which is why it was tagged with that.

What language would you have picked? Because most languages do not have empty statements evaluate to true, so the block would have had to be for(;1;); which is not as neat IMO

Using C and TCO:


#define foo(x) _foo((x),1,0)

int _foo(int to,int cur,int acc)
{
  if((cur = 0) || (to = cur))
  {
    return acc;
  }
  return _foo(to,cur+1,acc+cur);
}

int main(void)
{
  return foo(10);
}

C++

#include <iostream>
int main(int argc, char* argv)
{
    std::cout << "argc is " << argc << std::endl;
    std::cout << main(argc, argv);
    return main(1, {'H', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd', '\0'});
}

C++ (even though the syntax highlithing is set to python)

#include <my_awesome_events_manager_lib>
using namespace my_awesome_events_manager_lib;
int main(void)
{
    auto playing = true;
    while (playing)
    {
        // handle events /!\
        if (getEvent()->type == QUIT) playing = !playing;
    }
    return 0x0;
}
