Summary of Step 1 and Step 2: C# Basics

Step 1: Your First C# Program – “Hello, World!”

In the first step, you learned how to write your very first C# program. The program prints the text “Hello, World!” on the screen. This introduced you to the basic structure of a C# program, including:

• using System;: A statement that gives your program access to useful tools.
• class Program { ... }: The class is like a blueprint for your program.
• static void Main(): The Main method is where the program starts executing.
• Console.WriteLine("Hello, World!");: A command that tells the computer to display the text “Hello, World!” on the screen.

This step helped you understand how C# programs are structured and how you can display messages on the console.

Step 2: Variables and Data Types

In Step 2, you learned about variables and data types, which allow you to store and work with information in your programs. Key concepts include:

• Variables: These are like containers that store data. For example:

  string playerName = “Alice”;
  int playerAge = 12;

  • In this case, playerName is a variable that stores the text “Alice”, and playerAge stores the number 12.

  • Data Types: Every variable has a specific type that defines what kind of data it can hold:

    • string: Used for text (e.g., “Alice”).
    • int: Used for whole numbers (e.g., 12).
    • bool: Used for true/false values (e.g., true or false).
    • double: Used for decimal numbers (e.g., 3.14).

  You also practiced using variables in a program, such as:

Console.WriteLine("Player Name: " + playerName);
Console.WriteLine("Player Age: " + playerAge);

This helped you understand how to store information and display it, and how diffe

Key Takeaways:

• In Step 1, you learned how to display text on the screen with a simple C# program.
• In Step 2, you learned how to use variables to store and display information, and explored basic data types like string, int, bool, and double.
