🎯 What you will learn
- Where C# is used (Unity, apps, web)
- Write a console program
- Print with Console.WriteLine
👋 Let’s get started!
C# (say “C sharp”) powers Unity — the engine behind thousands of games 🎮 — plus Windows apps and websites. Modern C# lets you start with just one line!
🪜 Step by step
1. 🎮 Why C#?
C# runs on .NET, a free platform by Microsoft that works on Windows, Mac and Linux. Unity uses C# for game scripts.
2. ✍️ Top-level statements
In modern C#, a whole program can be a single line.
Console.WriteLine("Hello, C#!");3. 🏠 The classic structure
Bigger programs use namespaces, classes and a Main method — like Java.
class Program
{
static void Main()
{
Console.WriteLine("Hello from Main!");
}
}🧪 Try it!
Read the code, guess what it prints, then press 👀 Show output.
My first C# program
Console.WriteLine("Hello, C#! 🎮");
Console.WriteLine("Let the quest begin...");
Console.Write("No new line ");
Console.WriteLine("then a new line.");Classic program structure
class Program
{
static void Main()
{
Console.WriteLine("Ready!");
}
