C# Basics Tutorial
Welcome to C# Basics
This tutorial will guide you through the fundamentals of C#.
Basic Syntax
Let's start with the basics: `using System;`
This imports the System namespace, which contains essential classes and methods.
Variables
Variables are used to store data.
Example: `int age = 25;`
Data Types
Data types determine the kind of value a variable can hold.
- Integer: Whole numbers (e.g., 1, -5, 0)
- Single Variable: Represents one value (e.g., 10, -5)
- Double Variable: Can hold decimal numbers (e.g., 2.5, -1.0)
- String: Text (e.g., "Hello", 'C#')
Adding Variables
Let's add some variables:
int count = 10;
string message = "Welcome to C#!";
double price = 99.99;
Basic Statements
Statements are executed to perform actions.
Example: `Console.WriteLine("Hello");`
Conditional Statements
Let's use `if` to make decisions.
if (age >= 18) {
Console.WriteLine("You are an adult.");
} else {
Console.WriteLine("You are a minor.");
}
Looping
Loops repeat a block of code.
for (int i = 0; i < 5; i++) {
Console.WriteLine("Iteration: " + i);
}
