![HelloWorld]
This is the default introductory program to a new programming or scripting language.  The main purpose and goal of the program is to display the text string "Hello World\n" to the standard output stream ([stdout(3)]).

Some examples in different ProgrammingLanguages:

[BASIC]
 PRINT "Hello World\n"

[C]
 #include <stdio.h>
 int main(int argc, char **argv) {
   printf("Hello World\n");
   return 0;
 }

[C++]
 #include <iostream>
 void main(){
   cout << "Hello World" << endl;
 }

Linux x86 AssemblyLanguage
 .data
 .align 4
 message:
   .string    "Hello World\n"
 message_len = . - message

 .text
 .align 4
 .globl _start
 _start:
    movl $0x4, %eax
    movl $0x1, %ebx
    movl $message, %ecx
    movl $message_len, %edx
    int  $0x80
    movl $0x1, %eax
    xorl %ebx, %ebx
    int  $0x80



Well yeah, I could go on and on for different programming languages but there would be too many to list here[1].

[1] In fact there are hundreds of programming languages.
