在google里敲了“HelloWolrd”，再點“手氣不錯”，出來了這樣一個頁面：http://www2.latech.edu/~acm/HelloWorld.shtml

Hello World!

Welcome to the ACM "Hello World" project. Everyone has seen the Hello World program used as a first exposure to a new language or environment. We are attempting to collect examples for as many languages and related programming environments (shells etc.) as possible.

Aproximate number of examples:204     <----wow~~~

看看C的，經(jīng)典HelloWorld
#include <stdio.h>
main()
{
  for(;;)
      {
          printf ("Hello World!\n");
      }
}

這也是HelloWolrd？！
a 1986 entry from Bruce Holloway:

#include "stdio.h"
#define e 3
#define g (e/e)
#define h ((g+e)/2)
#define f (e-g-h)
#define j (e*e-g)
#define k (j-h)
#define l(x) tab2[x]/h
#define m(n,a) ((n&(a))==(a))

long tab1[]={ 989L,5L,26L,0L,88319L,123L,0L,9367L };
int tab2[]={ 4,6,10,14,22,26,34,38,46,58,62,74,82,86 };

main(m1,s) char *s; {
    int a,b,c,d,o[k],n=(int)s;
    if(m1==1){ char b[2*j+f-g]; main(l(h+e)+h+e,b); printf(b); }
    else switch(m1-=h){
        case f:
            a=(b=(c=(d=g)<<g)<'<g)<<g;
            return(m(n,a|c)|m(n,b)|m(n,a|d)|m(n,c|d));
        case h:
            for(a=f;a=e)for(b=g<<g;b<n;++b)o[b]=o[b-h]+o[b-g]+c;
            return(o[b-g]%n+k-h);
        default:
            if(m1-=e) main(m1-g+e+h,s+g); else *(s+g)=f;
            for(*s=a=f;a<e;) *s=(*s<<e)|main(h+a++,(char *)m1);
        }
}

曾經(jīng)最短的HelloWorld（Jari.Arkko@lmf.eua.ericsson.se）
jar.1.c
char*_="Hello world.\n";

ln -s /dev/tty jar.1.o
cc -c jar.1.c


現(xiàn)在最短的HelloWorld （Jyrki Holopainen）
