Open Notepad++ if it isn't open. Double-click the Notepad++ app icon, which resembles a white pad with a green frog on it.

Delete any text currently in Notepad++. You'll usually see some developer notes here, so just highlight and delete them.

Click Settings. This tab is at the top of the Notepad++ window. Clicking it prompts a drop-down menu.

Click Preferences…. It's in the Settings drop-down menu. Doing so opens the Preferences window.

Review your Notepad++ settings. Look over the settings in the middle of the window, or click a tab on the left side of the Preferences window to change the category of settings that you're viewing.

1. You can change these settings to your liking, but be careful not to change anything that you don't understand.

Click Close. It's at the bottom of the Preferences window. Doing so saves any changes and closes the window.

Review the menu buttons. Near the top of the Notepad++ window, you'll see a row of colored buttons. Hovering your mouse over each of the buttons will show you what each button does.

1. For example, the purple floppy disk-shaped icon in the upper-left side of the window saves your progress on a project when clicked.

Decide on a language. This article covers examples for C++, Batch, and HTML coding, but you can use almost any language that you want to with Notepad++. Once you have a language picked out, you can proceed with actually using Notepad++ to create a program.

Click the Language tab. It's at the top of the window. Clicking it prompts a drop-down menu.

Select C. You'll find this option in the Language drop-down menu. A pop-out menu will appear.

Click C++. It's in the pop-out menu. Most programmers' first experiences with C++ involve creating a program that says "Hello, World!" when run, so that's what you'll do here.^{[1] X Research source}

Add a title to your program. Type in // followed by your program's title (e.g., "My first program"), then press ↵ Enter.

1. Any text in a line that's typed after two slash marks won't be read as code.
2. For example: to entitle your program "Hi Earth", you'd type //Hi Earth into Notepad++.

Enter the preprocessor command. Type #include into Notepad++, then press ↵ Enter. This command instructs C++ to run the following lines of code as a program.

Declare the program's function. Type int main () into Notepad++, then press ↵ Enter.

Add an open bracket. Type { into Notepad++, then press ↵ Enter. Your program's main code will go between this open bracket and a closed bracket later.

Enter your program's execution code. Type std::cout << "Hello World!"; into Notepad++ and press ↵ Enter.

Add a closed bracket. Type } into Notepad++. This closes the program's execution phase.

Review your program. It should look something like this:

1. //Hi Earth
2. #include
3. int main ()
4. {
5. std::cout << "Hello World!";
6. }

Save your program. Click File, then click Save As... in the drop-down menu, enter a name for your program, select a save location, and click Save.

1. If you have a program on your computer that can run C++, you should be able to open your Hello World program in it.

Click the Language tab. It's at the top of the window. Clicking it prompts a drop-down menu.

Select B. You'll find this option in the Language drop-down menu. A pop-out menu will appear.

Click Batch. It's in the pop-out menu. Batch is a modified version of the commands that you use in Command Prompt, so any Batch file will open in Command Prompt.^{[2] X Research source}

Enter the "echo" command. Type @echo off into Notepad++ and press ↵ Enter.

Add a title for your program. Type in Title text and press ↵ Enter, making sure to replace "text" with your preferred title.

1. When you run the program, the title text is what will display at the top of the Command Prompt window.

Enter display text. Type in echo text and press ↵ Enter. Replace "text" with whatever you want Command Prompt to display.

1. For example, if you want Command Prompt to say "Humans are superior!", you'd type echo Humans are superior! into Notepad++.

Halt the program. Type pause into Notepad++ to indicate the end of the program.

Review your code. It should look something like this:

1. @echo off
2. Title Improved Command Prompt
3. echo Humans are superior!
4. pause

Save your program. Click File, then click Save As... in the drop-down menu, enter a name for your program, select a save location, and click Save.

1. If you want to run your program, simply find it in its save location and double-click it to do so.

Click the Language tab. It's at the top of the window. Clicking it prompts a drop-down menu.

Select H. You'll find this option in the Language drop-down menu. A pop-out menu will appear.

Click HTML. It's in the pop-out menu. HTML is commonly used for website pages, so you'll be creating a basic webpage heading and subheading.^{[3] X Research source}

Enter your document header. Type into Notepad++, then press ↵ Enter.

Add the "html" tag. Type into Notepad++ and press ↵ Enter.

Add the "body" tag. Type into Notepad++ and press ↵ Enter. This indicates that you'll be entering a section of text or other body information.

Enter your page's heading. Type in

text

and press ↵ Enter, making sure to replace the "text" section with your preferred page heading.

1. For example: to set your heading as "Welcome to my Swamp", you would type

   Welcome to my Swamp

   into Notepad++.

Add text below the heading. Type in

text

and press ↵ Enter. You'll replace "text" with your preferred text (e.g., "Make yourself right at home!").

Close the "html" and "body" tags. Type in and press ↵ Enter, then type in .

Review your code. It should look like this:

4. Welcome to my Swamp

5. Make yourself right at home!

Save your program. Click File, then click Save As... in the drop-down menu, enter a name for your program, select a save location, and click Save.

1. As long as you select your language before saving, Notepad++ will choose the correct file format for you.
2. You should be able to open your HTML file in any web browser.
