Free course on "Calculator implementation in C++ using Expression Grammar (context free grammar)" From Chapter 6 of the book "Programming: Principles and Practice using C++" by Bjarne Stroustrup. I have tried to share my learning experience while converting Expression Grammar into the Calculator program using C++. Hope, it will help people like me to understand the concepts in a faster way and help to resolve doubts. While coding the program, I am also sharing the thought process which goes on in developers mind. We will face compile-time, run-time errors and then we will resolve them using gdb debugger. Implementing Expression Grammar in C++ gives us a bit of understanding on how the parsing works. Instructor: Kashinath Chillal (Founder, Aloraq Software (OPC) Pvt. Ltd.) https://lnkd.in/gX8eXRK3

When modeling scenarios with a fixed set of outcomes — such as parsing user input or handling HTTP requests — developers often rely on enums or inheritance, which can compromise clarity and type safety. C# 15 introduces union types as a more robust alternative. These allow you to define a closed set of types with implicit conversions and pattern matching, ensuring compile-time exhaustiveness. This means the compiler will catch missing cases, reducing runtime errors. For example, a Result<int, Error> type cleanly represents success or failure, aligning with functional programming patterns and improving code safety. I believe union types offer a design shift that makes C# more expressive and safer — especially for handling domain events or API responses. What do you think — how have you handled similar scenarios before union types? #CSharp #DotNet #Programming #SoftwareDevelopment

Strategy Pattern in C# -- Animated Code Walkthrough Ever used a giant switch statement to handle different behaviors? There's a much cleaner way. In this short animated video, I walk you through the Strategy Pattern -- one of the most practical design patterns for real .NET projects. What you'll learn: -- The problem with switch/if-else chains -- How interfaces solve it elegantly -- Real C# code example -- Before vs After comparison -- Key takeaways for production code The Strategy Pattern lets you swap algorithms at runtime without touching the calling code. Open/Closed Principle in action! Which design pattern do you use most?

💡 𝐂#/.𝐍𝐄𝐓 𝐓𝐢𝐩 - 𝗗𝗲𝗰𝗹𝗮𝗿𝗮𝘁𝗶𝗼𝗻 𝗣𝗮𝘁𝘁𝗲𝗿𝗻 🔥 💎 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗶𝘁? Declaration patterns let you check the runtime type of an expression AND declare a new variable in one step. When the pattern matches, the variable is automatically assigned with the converted result. This eliminates the need for separate type checking and casting. ✅ 𝗞𝗲𝘆 𝗕𝗲𝗻𝗲𝗳𝗶𝘁𝘀 ◾ Combines type checking and variable declaration in a single, readable expression. ◾ Eliminates explicit casting and reduces boilerplate code. ◾ Prevents type mismatch errors with compile-time safety. ⚡ 𝗖𝗼𝗺𝗺𝗼𝗻 𝗨𝘀𝗲 𝗖𝗮𝘀𝗲𝘀 ◾ Type checking in if statements: if (obj is string text). ◾ Switch expressions with pattern matching. ◾ Processing collections with different element types. 🤔 Do you use declaration patterns in your code? #csharp #dotnet #programming #softwareengineering #softwaredevelopment

🔹 Tight Coupling vs Loose Coupling in C# 🔹 Understanding coupling is key to writing clean, maintainable, and scalable code in C#. Let’s break it down in a simple way 👇 👉 Tight Coupling When classes are highly dependent on each other, it’s called tight coupling. • One class directly creates or controls another class • Hard to modify or test • Changes in one class can break another 📌 Example: A class directly using new keyword to create another class inside it. 👉 Loose Coupling When classes are independent and interact through abstractions (like interfaces), it’s called loose coupling. • Easy to maintain and test • Flexible and scalable • Changes in one class don’t affect others much 📌 Example: Using Dependency Injection and Interfaces instead of direct object creation. 💡 Conclusion: Tight coupling makes code rigid ❌ Loose coupling makes code flexible and professional ✅ If you want to write better C# applications, always aim for loose coupling using principles like SOLID. #CSharp #DotNet #SoftwareDevelopment #CleanCode #Programming #Developers #Coding #DependencyInjection #SOLIDPrinciples #BackendDevelopment #TechLearning

.𝗡𝗲𝘁 𝟭𝟬 - 𝗖# 𝟭𝟰 𝗝𝘂𝘀𝘁 𝗠𝗮𝗱𝗲 𝗣𝗿𝗼𝗽𝗲𝗿𝘁𝗶𝗲𝘀 𝗖𝗹𝗲𝗮𝗻𝗲𝗿 - 𝗳𝗶𝗲𝗹𝗱 𝗸𝗲𝘆𝘄𝗼𝗿𝗱 In older C# code, if we wanted to add logic inside a property, we usually had to create a separate private variable. With C# 14, we can now use the 𝗳𝗶𝗲𝗹𝗱 keyword inside a property accessor. It gives direct access to the compiler generated backing field, so we can keep the code shorter and cleaner. 𝗕𝗲𝗳𝗼𝗿𝗲 public class Student { 𝗽𝗿𝗶𝘃𝗮𝘁𝗲 𝗶𝗻𝘁 _𝗺𝗮𝗿𝗸𝘀; public int Marks { get => _marks; set => _marks = value < 0 ? 0 : value; } } 𝗪𝗶𝘁𝗵 𝗳𝗶𝗲𝗹𝗱 𝗶𝗻 𝗖# 𝟭𝟰 public class Student { public int Marks { get; set => 𝗳𝗶𝗲𝗹𝗱 = value < 0 ? 0 : value; } } 𝗪𝗵𝗮𝘁 𝗰𝗵𝗮𝗻𝗴𝗲𝗱? We no longer need this line: private int _marks; The compiler creates the backing field for us, and field lets us use it directly inside the property accessor. 𝗪𝗵𝘆 𝘁𝗵𝗶𝘀 𝗶𝘀 𝘂𝘀𝗲𝗳𝘂𝗹 • Cleaner code. • Less boilerplate. • Same control over validation or simple logic. #dotnet #csharp #softwaredevelopment #dotnetdev #programming
