Understand the limitations of Notepad. Technically, we can write and launch a program in Notepad using any available programming language, but for the program to run, the file must be saved in the correct format.

By default, all Notepad files will be saved as text documents.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/47/Make-a-Program-Using-Notepad-Step-2.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/47/Make-a-Program-Using-Notepad-Step-2.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Find and open Notepad. The easiest way to open Notepad is to click Start

{“smallUrl”:”https://www.wikihow.com/images_en/0/07/Windowsstart.png”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/07/ Windowsstart.png/30px-Windowsstart.png”,”smallWidth”:460,”smallHeight”:460,”bigWidth”:30,”bigHeight”:30,”licensing”:”<div class=”mw-parser-output “></div>”}

, type notepad , and then select the Notepad icon at the top of the Start window.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/2e/Programlanguage.jpg/v4-728px-Programlanguage.jpg”,”bigUrl”:”https://www.wikihow. com/images/thumb/2/2e/Programlanguage.jpg/v4-728px-Programlanguage.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing” :”<div class=”mw-parser-output”></div>”}

Define programming language. Notepad doesn’t restrict any languages, but you need to use one language throughout the document to maintain consistency.

If you don’t know anything about programming languages, you can try one of the examples in this article.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/ce/Make-a-Program-Using-Notepad-Step-4.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/ce/Make-a-Program-Using-Notepad-Step-4.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Press ↵ Enter after you complete the line of code. Like most code editors, you need to add new lines of code to Notepad.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cf/Make-a-Program-Using-Notepad-Step-5.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-5.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cf/Make-a-Program-Using-Notepad-Step-5.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-5.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Close any opening brackets. Every time you open a brace (such as { or [ ), you must close it with the same mark on the opposite side to complete the line of code and not cause an error.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/9a/Considerusing.jpg/v4-728px-Considerusing.jpg”,”bigUrl”:”https://www.wikihow. com/images/thumb/9/9a/Considerusing.jpg/v4-728px-Considerusing.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing” :”<div class=”mw-parser-output”></div>”}

Consider using a dedicated code editor. While you can write almost any program in Notepad, it’s not necessarily the easiest way. Because Notepad doesn’t have any text highlighting or indenting options, it can be a bit difficult to write large pieces of code.

Notepad++ is a great free option for programming.

Create a program

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/cc/Make-a-Program-Using-Notepad-Step-7.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-7.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/cc/Make-a-Program-Using-Notepad-Step-7.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-7.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Open Notepad. How to create and save the program will depend on the programming language you use.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b0/Make-a-Program-Using-Notepad-Step-8.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-8.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b0/Make-a-Program-Using-Notepad-Step-8.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-8.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Enter the program code. You need to make sure that the language you are using is consistent throughout the document.

Create a basic BAT program

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d2/Make-a-Program-Using-Notepad-Step-17.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-17.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d2/Make-a-Program-Using-Notepad-Step-17.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-17.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Open Notepad. You can create a program that opens another program on your computer by using batch scripting (BAT).

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/37/Make-a-Program-Using-Notepad-Step-18.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-18.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/37/Make-a-Program-Using-Notepad-Step-18.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-18.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Enter the filename into the Command Prompt. Type cmd.exe into Notepad.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c6/Make-a-Program-Using-Notepad-Step-19.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-19.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c6/Make-a-Program-Using-Notepad-Step-19.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-19.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Save the program . You need to make sure you use the .bat extension when you save the program.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/6d/Make-a-Program-Using-Notepad-Step-20.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-20.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/6d/Make-a-Program-Using-Notepad-Step-20.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-20.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Double-click the BAT file. A new Command Prompt window will open.

Create a basic HTML program

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b2/Make-a-Program-Using-Notepad-Step-21.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-21.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b2/Make-a-Program-Using-Notepad-Step-21.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-21.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Open Notepad. Especially, if you are designing websites then HTML is a great language to use.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/61/Make-a-Program-Using-Notepad-Step-22.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-22.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/61/Make-a-Program-Using-Notepad-Step-22.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-22.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Specify that you will use HTML. Type <!DOCTYPE html> into Notepad and press ↵ Enter .

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/ac/Make-a-Program-Using-Notepad-Step-23.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-23.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/ac/Make-a-Program-Using-Notepad-Step-23.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-23.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Add HTML tags. You type <html> into Notepad and then press ↵ Enter .

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3d/Make-a-Program-Using-Notepad-Step-24.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-24.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3d/Make-a-Program-Using-Notepad-Step-24.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-24.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Set up body text. Type <body> into Notepad and then press ↵ Enter . This line specifies that the next section of the document will contain information (in this example, text).

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/4/4c/Make-a-Program-Using-Notepad-Step-25.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-25.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/4/4c/Make-a-Program-Using-Notepad-Step-25.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-25.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Add a page title. Type <h1>Text</h1> into Notepad and press ↵ Enter , remembering to replace “Text” with what you want the page title to be.

For example, to create a page with the title “Hello!”, you would type <h1>Xin chao!</h1> into Notepad.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/7e/Make-a-Program-Using-Notepad-Step-26.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-26.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/7e/Make-a-Program-Using-Notepad-Step-26.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-26.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Add text to the page. Type <p>text</p> into Notepad and then press ↵ Enter . Don’t forget to replace “text” with your own text.

For example, when you type <p>Hom nay ban khoe khong?</p> into Notepad, the sentence “How were you today?” will appear below the title.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8d/Make-a-Program-Using-Notepad-Step-27.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-27.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8d/Make-a-Program-Using-Notepad-Step-27.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-27.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Close the content section. Type </body> into Notepad, then press ↵ Enter .

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/9/92/Make-a-Program-Using-Notepad-Step-28.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-28.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/9/92/Make-a-Program-Using-Notepad-Step-28.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-28.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Specify the end of the HTML code. You enter </html> into Notepad.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f3/Make-a-Program-Using-Notepad-Step-29.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-29.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f3/Make-a-Program-Using-Notepad-Step-29.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-29.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Review the program’s code. The code will look similar to this:

<!DOCTYPE html>
<html>
<body>
<h1>Xin chao!</h1>
<p>Hom nay ban khoe khong?</p>
</body>
</html>

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/31/Make-a-Program-Using-Notepad-Step-30.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-30.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/31/Make-a-Program-Using-Notepad-Step-30.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-30.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Save the program . You need to make sure you use the .htm extension when saving.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f7/Make-a-Program-Using-Notepad-Step-31.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-31.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f7/Make-a-Program-Using-Notepad-Step-31.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-31.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Double-click the HTML file. This usually opens the program in the default web browser, or sometimes you need to select the program first. The title and body text will appear.

Creating a Basic Python Program

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5e/Make-a-Program-Using-Notepad-Step-32.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-32.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5e/Make-a-Program-Using-Notepad-Step-32.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-32.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Close the “print” command. Type ") into Notepad to close the command.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d7/Make-a-Program-Using-Notepad-Step-36.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-36.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d7/Make-a-Program-Using-Notepad-Step-36.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-36.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Review your code. The code will look similar to this:

print("Xin chao!")

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/23/Make-a-Program-Using-Notepad-Step-37.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-37.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/23/Make-a-Program-Using-Notepad-Step-37.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-37.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Save the program . Make sure you use the .py extension. You should now be able to open the program with your usual Python editor.

Creating Basic C++ Programs

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/6f/Make-a-Program-Using-Notepad-Step-38.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-38.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/6f/Make-a-Program-Using-Notepad-Step-38.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-38.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Open Notepad. We’ll use Notepad to create a basic C++ program that displays the text “Hello everyone!” at launch.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/19/Make-a-Program-Using-Notepad-Step-39.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-39.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/19/Make-a-Program-Using-Notepad-Step-39.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-39.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Add a title to the program. Enter // along with the title of the program (eg “Program 1”). Anything entered on the same line followed by two slashes will also display as plain text, but this is not part of the program.

For example, to set the title “Program 1” for the program, you type //Chuong trinh 1 into Notepad.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b0/Make-a-Program-Using-Notepad-Step-40.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-40.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b0/Make-a-Program-Using-Notepad-Step-40.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-40.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Enter the preprocessor command. Type # include <iostream> into Notepad and press ↵ Enter . This command instructs C++ to launch the next lines of code as a program.

{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0c/Make-a-Program-Using-Notepad-Step-41.jpg/v4-728px-Make-a-Program- Using-Notepad-Step-41.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0c/Make-a-Program-Using-Notepad-Step-41.jpg/ v4-728px-Make-a-Program-Using-Notepad-Step-41.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}

Advice

C++ and HTML are the two most commonly used programming languages.
You can use any programming language to write most programs, however some languages may be better suited for specific features (for example, HTML is ideal for creating webpage).

Warning

Always test your code before saving. If you save a corrupted program, it may cause the default assembler to fail.
