Hello, World!' - In Lotsa Languages!

Basic
--------------------------------------------------------------------------------

10 print"Hello World!"
20 goto 10


        Here's a 'Hello, World!' program written in Atari Basic:


10 REM HELLO.BAS
20 POKE 764,255
30 PRINT "Hello World"
40 IF PEEK(764)=255 THEN GOTO 30



C
--------------------------------------------------------------------------------

#include <stdio.h>

main()
{
for(;;)
{
printf ("Hello World!\n");
}
}


    ... and a more complex one ...


#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);
}
}



C++
--------------------------------------------------------------------------------

Here we have an old version ...

#include <iostream.h>

main()
{
for(;;)
{
cout << "Hello World! ";
}}


    ... and a more modern one!


#include <iostream>

int main()
{
std::cout << "Hello, world!\n";
}
