Prerequisites

Before we begin, ensure you have the following installed on your system:

• Development Environment: Latest version of Visual Studio (or your preferred IDE).
• SDK: The relevant SDK for your target platform. You can download it from the Downloads page.
• Version Control: Git installed and configured.

Setting Up Your Project

Let's create a new project. Open your IDE and select "Create New Project". Choose the appropriate template for a simple console application.

Example Project Setup (Conceptual):

File -> New Project -> Console Application (e.g., C#, Python, Node.js)
Project Name: MyFirstApp
Location: C:\Development\MyFirstApp
                

Once the project is created, familiarize yourself with the project structure. You'll typically find a main file (e.g., Program.cs, main.py, app.js) where your code will reside.

Writing Your First Code

Open the main file of your project and replace its content with the following simple code:

// This is a simple "Hello, World!" program
Console.WriteLine("Hello, World!");
// Or for Python:
# print("Hello, World!")
# Or for JavaScript:
// console.log("Hello, World!");
                

This code will simply print the message "Hello, World!" to the console when the application is run.

Running Your Application

Now it's time to see your code in action!

1. Build: In your IDE, go to Build and select Build Solution (or equivalent). This compiles your code.
2. Run: Go to Debug and select Start Debugging (or press F5/Ctrl+F5).

You should see a console window appear, displaying the output:

Hello, World!
