Empty Program

Empty Program is a program that doesn't do anything.

In Python, you just write nothing (a null program) to do it. But in C++, you need to write a main function with no operation except return 0.

C++

int main()
{
    return 0;
}

Java

public class EmptyProgram(){
    public static void main(){
        // TODO
    }
}

Pascal

begin
  // TODO
end
.

C

int main(){}

PHP

<?php
?>

Go

package main()

func main(){
  // TODO
}

C♯ Mono

using System;

public class Empty(){
    private static void Main(){
        // TODO
    }
}

G#

make e; [
    return {an argument that won't do anything}
]
make main; [
    f[e]{}
]

JavaScript(Node.JS)

process.exit()

Batch File

@echo off
GOTO end
:end

Assembly Language

assume cs:codesg
codesg segment
start:
    mov cx, 0
    jcxz end
end:
    mov ah, 4ch
    int 21h

end start
