Hello-World

The very first thing you'll do when learning a new programming language is how to make the computer display "Hello, World". Let's have a look at how is the quote printed in some familiar programming languages- ALGOL, Assembly Language, Bash, C, Clipper, C++, C#, COBOL, CoffeeScript, FORTAN, Java, JavaScript, Julia,Mathematica (Wolfram Language), Machine Code, MATLAB, ML, NODE.Js, Pascal, Perl, PHP, Python, R, Ruby, Rust, Scala, Swift, VisualBaisc.NET.

ALGOL

BEGIN DISPLAY("HELLO WORLD!") END.

Assembly language

global  _main
    extern  _printf

    section .text
_main:
    push    message
    call    _printf
    add     esp, 4
    ret
message:
    db  'Hello, World', 10, 0

Bash

echo "Helloworld"

#include <stdio.h>

int main(void)
{
    printf("hello, world\n");
}

C++

#include <iostream>
int main()
{
 std::cout << "Hello, world!\n";
 return 0;
}

using System;
class Program
{
 static void Main(string[] args)
 {
 Console.WriteLine("Hello, world!");
 }
}

Clipper

?"Helloworld"

CoffeeScript

console.log 'Hello, world!'

COBOL

 IDENTIFICATION DIVISION.
 PROGRAM-ID. hello-world.
 PROCEDURE DIVISION.
 DISPLAY "Hello, world!".

FORTAN

program helloworld
 print *, "Hello world!"
end program helloworld
Java
class HelloWorldApp {
 public static void main(String[] args) {
 System.out.println("Hello World!"); // Prints the string to the console.
 }
}

Java

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

JavaScript

console.log("Hello World!");

cd 80 #executing it via linux sys_call

Julia

println("Hello world!")

Mathematica (Wolfram Language)

CloudDeploy["Hello, World"]

MATLAB

classdef hello
 methods
 function greet(this)
 disp('Hello, World')
 end
 end
end

print "Hello world!\n";

Node.Js

console.log("Hello World!");

Pascal

program HelloWorld(output);
begin
 Write('Hello, world!')
end.

Perl

print "Hello, World!\n";

PHP

<?php echo "Hello, World";

Python

print("Hello World")

cat('Hello, world!')

Ruby

puts 'Hello World!'

Rust

fn main() {
 println!("Hello, world!");
}

Scala

object HelloWorld extends App {
 println("Hello, World!")
 }

Swift

println("Hello, world!")

VisualBasic.NET

Module Module1
    Sub Main()
        Console.WriteLine("Hello, world!")
    End Sub
End Module
