So, It’s: Python vs JavaScript vs Bash vs C vs C# vs C++ vs Assembly vs Java vs Perl vs Go vs HTML vs PHP vs Swift.
Some people say that learning to “Hello world” is half the language, so
Let’s start the fight.
Python – the easiest.
It’s simple.
print("Hello world")
Javascript – the semicolon paradox.
Always HATED the semicolon…
alert("Hello World");
Bash – shell out.
The heart of the shell. I prefer zsh though.
#!/bin/bash
echo "Hello World!";
C – can you ‘see‘
The one that rules them all (after assembly, of course…)
#include<stdio.h>
int main(void) {
printf("Hello World\n");
return 0;
}
C# – too sharp
The C version of Java (and, I don’t like Java that much…)
namespace HelloWorld
{
class Hello {
static void Main(string[] args)
{
System.Console.WriteLine("Hello World!");
}
}
}
C++ – C improved (I suppose)
Did you get the vim joke?
#include <iostream>
using namespace std;
int main() {
cout << "Hello, World!" << endl;
return 0;
}
Assembly – the “real” king
We must assemble to be able to learn this.
section .text
global_start ;must be declared for linker (ld)
_start: ;tells linker entry point
mov edx,len ;message length
mov ecx,msg ;message to write
mov ebx,1 ;file descriptor (stdout)
mov eax,4 ;system call number (sys_write)
int 0x80 ;call kernel
mov eax,1 ;system call number (sys_exit)
int 0x80 ;call kernel
section .data
msg db 'Hello, world!', 0xa ;string to be printed
len equ $ - msg ;length of the string
I can’t even find syntax highlighting
Java – the coffee cup
I always wanted to taste that coffee.
public class java {
public static void main(String[] args) {
System.out.println("Hello World");
}
}
Perl – just ‘perl’
The perl of the shell.
#!/usr/bin/perl
print "Hello World\n";
Go – let’s go
There’s an animal in the logo.
package main
import "fmt"
func main() {
fmt.Println("Hello world")
}
No syntax highlighting here TOO, weird…
HTML – they say it’s a markup language.
Not a real programming language.
<!DOCTYPE html>
<html>
<head>
<title>Hello world</title>
</head>
<body>
<h1>Hello world</h1>
</body>
</html>
PHP – HTML organizer.
The most used web language yet.
<?php
print("Hello World");
?>
Swift – apple special
Exactly like Python, but too expensive.
print("Hello world")
And as someone once said
Good Bye everyone
and it was me…
