Introduction

When you plan to start learning a programming language, the very first program would most possibly to display "Hello, World!".

Let's see how can we write it in 30 different languages.

Let's Go!!!

➊ C

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

➋ C++

#include <iostream>
using namespace std;

int main() {
  cout << "Hello, World!";
  return 0;
}

➌ Java

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

➍ C#

Console.WriteLine("Hello, World!");

➎ HTML

<!DOCTYPE html>
<html>
  <body>
    Hello, World!
  </body>
</html>

➏ CSS

body::before{
 content: "Hello, World!";
}

➐ JavaScript

console.log('Hello, World!');

➑ Python

print('Hello, World!')

➒ PHP

<?php
echo "Hello, World!";

➓ Rust

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

➊➊ Objective-C

#import <Foundation/Foundation.h>

int main(int argc, char * argv[]) {
   NSLog(@"Hello, World!");
   return 0;
}

➊➋ Swift

print("Hello, World!")

➊➌ Kotlin

fun main(args : Array<String>) {
   println("Hello, World!")
}

➊➍ Dart

void main(){
   print("Hello, World!");
}

➊➎ Ruby

puts "Hello, World!"

➊➏ Groovy

println "Hello, World!"

➊➐ R

print("Hello, World!")

➊➑ MATLAB

disp('Hello, World!')

➊➒ Lua

print("Hello, World!")

20. Pascal

program Hello;
begin
  writeln ('Hello, World!');
end.

➋➊ Haskell

main = putStrLn "Hello, World!"

➋➋ Julia

println("Hello, World!")

➋➌ Perl

print("Hello, World");

➋➍ Elixir

IO.puts("Hello, World!")

➋➎ Golang

package main

import "fmt"

func main() {
   fmt.Println("Hello, World!")
}

➋➏ Clojure

(ns clojure.examples.hello
   (:gen-class))
(defn hello-world []
   (println "Hello World"))

➋➐ PL/SQL

BEGIN
dbms_output.put_line(‘Hello, World!');
END;
/

➋➑ Bash

echo "Hello, World!"

➋➒ Power Shell

Write-Host 'Hello, World!'

30. Solidity

pragma solidity >=0.5.0 <0.7.0;
contract HelloWorld {
   function get() public pure returns (string memory) {
      return 'Hello, World!';
   }
}

Final Words

I hope these code snippets would have given you an overall idea about the similarities and diversities among all these programming languages. And, I am hopeful that this article would help you to start in any of these languages.
