For my first test post I’ll just write Hello World! in a bunch of different ways.

C++

#include <iostream>
int main()
{
  std::cout << "Hello World!" << std::endl;
  return 0;
}

C

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

Java

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

Rust

fn main()
{
  println!("hello World!");
}

Bash

user@computer:~/$ echo 'Hello World'

python 2.7

>>> print 'Hello World'

python 3.x

>>> print('Hello World')
