How to Write Code in Windows Notepad

Windows Notepad is a very basic text editor that comes pre-installed on all Windows Operating Systems.

Notepad may be quite simple with no syntax highlighting or Intellisines like other tools like Notepad++, but that does not stop you from writing any kind of programming or scripting code in Notepad.

Let's take a look at how to write and run "Hello World" code in Notepad for 5 popular programming languages.

Note: For all the below examples you will need respective language software installed to compile and execute the programs using CMD/Terminal.

JavaScript:

<!DOCTYPE html>
<html>
<body>

<script>
    document.write("Hello, World!");
</script>

</body>
</html>

Make sure to save the file with .html extension.

You can open this HTML file in a web browser (such as Microsoft Edge or Google Chrome) to see the output.

Python:

print("Hello, World!")

Save the above Python code with a ".py" extension (e.g., hello.py):

To run this code, open Command Prompt or Terminal on your Windows PC, navigate to the folder where the hello.py file is located, and then run:

python hello.py

Java:

public class HelloWorld {
    public static void main(String... args) {
        System.out.println("Hello, World!");
    }
}

To run it, open Command Prompt, navigate to the folder containing HelloWorld.java, and compile and run it using these commands:

javac HelloWorld.java

java HelloWorld

C++:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Make sure to save the file as hello.cpp

Ruby:

puts "Hello, World!"

Make sure to save the file as hello.rb, to run it, open Command Prompt and run:

ruby hello.rb
