Source Code for this Article

HelloWorld.zip

If you have Programmed the Computer in any language, then you must heard about the "Hello World!" Program, this is the First Step in order to understand any Programming Language.

"Hello World" Program is first mentioned by the Developer of "C" Language by Brian Kernighan and D. Ritche, in his Golden Book "The C Programming Language", where he has been Described the "Hello World" Program in the Whole book. Which Print "hello, world" to the Screen.

Here I am Going to Define "Hello World" Program in more then 50 Languages, thinking that this will help u to Start learning new Languages or will give you the Over View to a New Language, If you get confused on a term then consult here!, or Click here to see the Index of the Programming Language.

If you want to save the Page for future use, Don't save by the browser, all the Code and this Article is included in the Zip file, Download HelloWorld.zip.

I have made all efforts to make the Codes Correct, If you see any error or have Comments, then mail me with Subject Line HELLO WORLD:.

In Order to Complete the Article, There are Some People who Help me to Complete the List. The List is So Long.

 Assembly Language                          ì

Ö Source Code : Hello.asm

DATA SEGMENT     MSG DB "Hello, World!","$" DATA ENDS CODE SEGMENT     ASSUME CS:CODE, DS:DATA START:     MOV AX, DATA                      ;INTILIZE     MOV DS, AX     MOV AH, 09H                       ;PRINT STRING     LEA DX, MSG     INT 21H STOP:     MOV AX, 4C00H                     ;TERMINATE     INT 21H CODE ENDS END START

Instructions To Run:

Assumed : Microsoft Assembler [MASM]
Open Dos Prompt, and use these Command, [Path where MASM is Installed.]
C:\>MASM Hello.asm
C:\>LINK Hello
If Successful [No Error Occurs] then Run
C:\>Hello.exe

Description:

All the Assembly Language Program have two Sections[Segment] DATA and CODE. Data Segment Defines the Variables, It can be of type

1. DB [Define Byte] 1 Bytes
2. DW [Define Word] 2 Bytes
3. DQ 4 Bytes
4. ** 8 Bytes

Look at the Program, MSG is the Name of Variable, it's type is DB, after that the initial value is given. The Code Segment Defines the Actual Code to be run. First notice the Assume keyword, which says the compiler to use this Segment as DATA and CODE, not to say that there can be more then one Data and Code Segments.

START and STOP are the Labels. Next two Statement Initialize the Data Segment, and must be used in all the Programs. Next three Statements will print the MSG Variable to the Screen. Notice the Statement INT 21H will generate Interrupt 21H, and its argument is saved in Register AH with Value 09H [in HexaDecimal format], which actually whatever is stored in Register DX i.e. Variable MSG. After STOP Label these two statements will Actually Terminate the Program, and must be used in all the program.

 C Language                              ì

Ö Source Code : Hello.c

#include<stdio.h> void main() {   //COMMENTS   printf("Hello World!\n"); }

Instructions To Run:

Assumed : Turbo C++ Compiler, Paste It in TC Editor or Open file Hello.c in the Editor, then Press F9 to Compile if there is no error then Ctrl+F9 to Run.

Description:

The First line #Include Says to Compiler that Attach this header file in Executable file, Which has the Definition for the Functions Used by our Program e.g. printf. Next statement is the Main Entry Point [main function], which start running as the Program Loads. Next the { is the Opening Symbol for the Main Function. Next we use a single line Comments, we can write any thing in this line for ourselves. Next we are calling printf function and passes the String as the argument, Notice the \n in string which cause to print special character New Line. this printf function will cause to Print the String to Screen. finally } is the closing brace for main function, which will stop the progam.

 C++                                 ì

Ö Source Code : Hello.cpp

#include <iostream.h> int main() {  //COMMENTS  cout << "Hello World!" << endl;  return 0; }

Instructions To Run:

Assumed : Turbo C++ Compiler.
Open file Hello.cpp in the Editor, then Press F9 to Compile if there is no error then Ctrl+F9 to Run.

Description:

First the #include works same like it in C, i.e Cause the iostream.h file to be included in the Executable. Next we define the main function which return an Integer type Data. Next the Single line Comment [ignored by compiler]. Next the cout is the Object not the function [as in C], and << is the operator of the object cout, and pass the String, next the endl will cause same as \n in C means causes the New Line character to be print on screen. finally the cout will cause the string to be printed in the Screen. Next the Return will tell the function to pass 0 to it's Caller. You will think that who is calling the main function. It's the Operating System which call the main function as the Program Loads in the Main Memory. Next is the Closing Brace which causes the Program to Stop running.

 Pascal                                ì

Ö Source Code : Hello.pas

program HelloWorld(output); begin  WriteLn('Hello World!'); end.

Instructions To Run:

Assumed : Turbo Pascal
Open file in the Editor, then Press F9 to Compile if there is no error then Ctrl+F9 to Run.

Description:

First We Define the Program name, Next the begin and end designate the Starting and Stop point of the Program. Next the WriteLn function will cause to Print the String to the Screen. Note that all the Statement are terminated with Semicolon.

 Cobol [ COmmon Business Oriented Language ]              ì

Instructions To Run:

Assumed : COBOL 80
C:\>COBOL Hello;
C:\>RUNCOB Hello

Description:

I have used MS COBOL 80, because it is simple, Traditionally COBOL Program is Most difficult to run Correctly, by newcomers. In this Version no exe will be created, you have to use RUNCOB to run your object program, however there are many compilers which generate exe file, such as MF COBOL [by Micro Focus] etc.

First there are four Division [Parts] in the COBOL program.

1. IDENTIFICATION DIVISION.
2. ENVIRONMENT DIVISION.
3. DATA DIVISION.
4. PROCEDURE DIVISION.

Each Division will contains Para and each Para will contain Statements. First line is Actually Comments,

Note the Spaces before each statements, it is not the indentation, you must provide it as is. In Each line First 3 Characters are Page number, next three character are Line Number, 7th character is special will be blank or * for Indicating Comments or - for indicating Continue last line. We Start our program from the 8th character. I don't uses any Page or line number so i place Space, If you omit Space or misplace it then you will surely get lots of Error, and the Error Message of COBOL are just like Hell.

Program-ID defines the Program name, and must be there in all the programs. Next in Procedure Division we define the Para main as Main Section, which actually contain the Statements to be run. Display statement will cause the Corresponding string to be print on Screen. Next the Stop Run will cause the Program to Terminate.

 Fortran [ FORmula TRAnsalation ]                    ì

C:\>Hello.Exe

Description:

First line is Calling function Write and print String to the Screen, the (*,*) will cause autometic formatting of the string, otherwise we have to provide our custom format. Next the End statement will cause the program to terminate.

Note the Spaces before each statements, it is not the indentation, you must provide it as is, otherwise it will cause errors.

Next we Define a Class named HelloWorld. Next is the Main function [which will automatically run as the program loads]. note the public static before main, it must be there because main function is defined insight the class, which means that it can't be called from outside until it is not declared as public member of the class. Next is the WriteLn function which print the specified string on screen, note that the WriteLn function is the member of Console Object.  return 0 means that this program tells the OS[the Caller of the Program] that the program is successfully runs.

This is the Code, that i use for Compiling, Linking and Running and even Creating New file for my Assembly Language [MASM] Files. Otherwise i need to provide lost of command to create a single Program. here i use commands

C:\MASM\>ASM NEWFILE
For creating new file named NEWFILE.ASM based on the Template file.

C:\MASM\>ASM File1
To Compile file file1.asm, if error then open file1.asm and ErrorLog for Edit, If no error then Link, If Error then display Error Massage, otherwise Run the Executable.
