Control Structures in C# 🚀 Control structures help control the flow of execution in a program. C# provides conditional statements ( if-else , switch ) and loops ( for , while , do-while ) to handle different scenarios. 1️⃣ Conditional Statements 🔹 if-else Statement The if-else statement executes code based on conditions . Syntax: if (condition) { // Code runs if condition is true } else if (anotherCondition) { // Code runs if anotherCondition is true } else { // Code runs if none of the above conditions are true } Example: int age = 20; if (age >= 18) { Console.WriteLine("You are an adult."); } else { Console.WriteLine("You are a minor."); } ✅ Nested if-else int number = 10; if (number > 0) { if (number % 2 == 0) { Console.WriteLine("Positive Even Number"); } else { Console.WriteLine("Positive Odd Number"); } } 🔹 switch Statement The switch statemen...

Variables, Data Types, and Operators in C# 🚀 Understanding variables, data types, and operators is essential for writing C# programs. Let’s go step by step. 1️⃣ Variables in C# A variable is a named storage location that holds data. 🔹 Declaring Variables dataType variableName = value; Example: int age = 30; string name = "John"; double price = 99.99; 🔹 Variable Naming Rules ✅ Must start with a letter or underscore ( _ ) ✅ Can contain letters, digits, and underscores ✅ Case-sensitive ( myVar and MyVar are different) ✅ Cannot use C# keywords (e.g., int , class , public ) 2️⃣ Data Types in C# C# has value types (stored directly in memory) and reference types (stored as references). 🔹 Common Value Types Data Type Size Example Description int 4 bytes int x = 100; Stores whole numbers double 8 bytes double pi = 3.14; Stores decimal numbers float 4 bytes float price = 9.99f; Smaller decimal precision char 2 bytes char grade...

Setting Up Your C# Development Environment 🚀 Setting Up Your C# Development Environment If you’re ready to dive into C# and .NET development , the first step is setting up a proper environment. This includes installing the .NET SDK , choosing an IDE , and configuring essential tools. 1️⃣ Install the .NET SDK The .NET SDK provides everything you need to build, run, and publish .NET applications. ✅ Download & Install .NET SDK Visit the official .NET download page: https://dotnet.microsoft.com/download Download the latest .NET SDK (LTS version recommended). Run the installer and follow the instructions. ✅ Verify Installation dotnet --version If installed correctly, you’ll see the installed .NET version . 2️⃣ Choose an IDE (Integrated Development Environment) You need an IDE or code editor to write ...

1️⃣ What is .NET? 🔹 .NET (Dotnet) is a free, open-source, cross-platform framework developed by Microsoft for building various types of applications, including: Web Applications Desktop Applications Cloud Services Mobile Apps Game Development IoT Applications 🔹 Key Characteristics of .NET ✅ Cross-platform – Runs on Windows, macOS, and Linux ✅ Language Interoperability – Supports multiple languages, including C#, F#, and VB.NET ✅ High Performance – Optimized runtime for fast execution ✅ Managed Code – Uses the Common Language Runtime (CLR) ✅ Automatic Memory Management – Uses Garbage Collection (GC) 2️⃣ Evolution of .NET .NET Framework (2002) – The original, Windows-only version .NET Core (2016) – A cross-platform, modular, open-source version .NET 5+ (2020-Present) – A unified platform (merging .NET Framework and .NET Core) 🔹 Current Version : .NET 8 (Latest as of 2024) 🔹 Major Components of .NET .NET Runtime – Execut...
