B. Setting up your Lua development environment

To start programming in Lua, you'll need to set up your development environment:

1. Download Lua from the official website
2. Install Lua on your system
3. Choose a text editor or IDE (e.g., Visual Studio Code with Lua extension)
4. Set up the Lua interpreter in your system's PATH

C. Writing your first Lua program

Now, let's create a simple "Hello, World!" program in Lua:

print("Hello, World!")

To run this program:

1. Save it as hello.lua
2. Open a terminal or command prompt
3. Navigate to the directory containing your file
4. Type lua hello.lua and press Enter

This will output "Hello, World!" to the console. With your environment set up and your first program running, you're ready to explore more complex Lua concepts and features.
