C# Basics

1. Getting Started

Why C#?C# Syntax Displaying Output Challenge: Outputting a Triangle Comments Challenge: Comments Variables Identifiers Challenge: Variable Declaration Basic Operators & Expressions Challenge: Operators

2. Dealing with Data Types

Integer Data Types Challenge: Declaring Explicitly Typed Variables Floating-Point and Double Booleans Character String Strings Challenge Basic String Formatting Challenge: String Formatting Declaring Constants Basic Type Casting Type Casting Practice Basic Type Conversion Basic Coding Practice

3. Control Structures

Comparison Operators Logical Operators Challenge: Operators Order of Operations If Statement Challenge: if Condition else Keyword Challenge: else Keyword if-else Chain Challenge: if, else-if, else switch Statement Challenge: Switch

4. Loops

for Loop Challenge: for Loop while Loop do-while Loop Challenge: do-while Loop break Statement continue Statement Challenge: break and continue

5. Arrays

What are Arrays?Challenge: Array Declaration Indexing Challenge: Indexing Multi-Dimensional Arrays Challenge: Multi-Dimensional Arrays Looping through Arrays Challenge: Array Loops

6. Methods

What are Methods?Creating and Calling Methods Challenge: Methods Creation Method Parameters Challenge: Method with Parameters Method Return Values Challenge: Return Values Local & Global Scopes Challenge: Scopes What's Next?

Booleans

Boolean data type represents two logical values true and false. The keyword bool can be used to create a Boolean variable:

main.cs


              12345678910111213141516
            
using System;

namespace ConsoleApp
{
  internal class Program
  {
    static void Main(string[] args)
    {
      bool isOnline = true;
	  Console.WriteLine(isOnline); // Output: True

	  isOnline = false;
	  Console.WriteLine(isOnline); // Output: False
    }
  }
}

Logical values are used especially where we want to execute a piece of code based on a specific condition. We will learn more about conditional statements in the next section.
