Lets post as many different variations of the 'hello world' program in as many different coding languages as we can. Just to give that little used 'code' button some exercise [Wink]

I'll go first: C++ (of course!)

code:

#include <iostream.h>

int main()
{
    cout << "Hello world!\n";
    return 0;
}

VB.NET

Console App

code:

 
Module Module1

    Sub Main()
        Console.WriteLine("Hello World!")
    End Sub

End Module

Windows App

code:

 
Public Class Form1
    Inherits System.Windows.Forms.Form

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        MessageBox.Show("Hello World!")
    End Sub
End Class

HTML. Feel free to link a stylesheet and dandy up the "Hello World!"

How bout some C

code:

 
#include<stdio.h>
int main()
  {
     printf("Hello World!\n");
     return 0;
   }

Posted by Katarain (Member # 6659) on :

It's been so many years... let's see if I can get this right..

10 cls
20 print "Hello World!"
30 goto 20

We used to play around and make our old IBM XT without a harddrive play music and write in color. I forget all that.

[Big Grin]

What is that called, anyway... basic?

code:

public class HelloWorld{
    public static void main(String[] args){
        System.out.println("Hello World!");
    }
}

Edit: its very hard to avoid the urge to hit tab after a line to indent it! Too much IDE's.

Oh and this is java of course.

(DEFUN HELLO-WORLD () (PRINT (LIST 'HELLO 'WORLD)))

LISP. I miss this language...

Posted by Dagonee (Member # 5818) on :

Visual Basic For Applications (Word)

code:

Sub HelloWorld()
    Dim doc As Word.Document
    Set doc = Application.Documents.Add()
    doc.Range().InsertAfter "Hello World"
End Sub

Edit: Even shorter version:

code:

Sub HelloWorld()
    Application.Documents.Add().Range().InsertAfter "Hello World"
End Sub

PHP, of course -

code:

<?php

echo 'Hello World!';

?>

Prolog -

code:

hello(D) :- 
   write('hello world'),
   New is D -1,
   hello(New).

hello(0).

You know I listed LISP on my resume?

One of the engineers said I "had balls" to list that [Smile]

. I got the job, so yay for LISP.

PL/SQL -

code:

DECLARE
msg varchar(50);
BEGIN
Select text into msg from hello_tbl where world = 1;
END;
PRINT :msg;
.
run;

Can any other languages do infinite precision integer arithmetic? That's what's so cool about Lisp. It's great for doing number theory stuff, finding prime numbers and printing out every digit of 10,000 factorial or the first million digits of pi or things like that.

I'm about 10 years out of date in programming skillz, though, so likely there's something else way better now. But I just don't know what.

I bet I'm the only one here who's written code in IBM 370 JCL, or DEC PDP-11 machine language. Or how about PL/1? <laughs> A dubious distinction, at best.

My aunt helped write one of the first assemblers at Rand Corporation in the 50s before there were computer science majors (she majored in Math).

When I started my first programming job in 1982 I worked with a guy who had started out soldering boards in order to write his programs. They actually did that at one point, used a solder gun and little wires to write their code, then plugged the board into the slot to run the program. <boggles>

Ahhh... Ada. Barf. It's what we used in my into CS class. Good ol Dr. Atkins. I guess WVU had some kind of deal with the military to teach ada. Dr. Atkins was a great teacher. Hard as heck tests. But after his class every other CS class was a review.

Many modern languages allow arbitrary precision arithmetic. Python, Ruby, Perl, all do it effortlessly (actually, never tried in Perl, but I'm pretty sure it can). Java can do it without much trouble.

Posted by Gregg (Member # 6752) on :

The C++ ones are just a tad C dependent. Here is another variation:

code:

#include <iostream>
using namspace std;

int main()
{
    cout << "Hello world!" << endl;
    return 0;
}

Well, yes, pretty much any computer language we're discussing is Turing complete, and can thus calculate in arbitrary precision arithmetic in some way/shape/form. The ones I listed make it easy, though [Wink]
