🔹 Part 1: SFINAE in C++ This short video is part of my "C++ Programming Topics" series 👇 And also included in my broader C++ templates playlist. 💡 The problem: Many developers struggle with controlling which template functions should participate in overload resolution. This can lead to: -Confusing compiler errors -Unintended function matches -Less robust generic code ❌ 📌 This is where SFINAE becomes powerful: 👉 Substitution Failure Is Not An Error allows the compiler to silently discard invalid template instantiations. 💡 The solution: Applying SFINAE techniques to a simple example: int sum(int a, int b) { return a + b; } ✔️ Constrain templates to valid types only ✔️ Prevent invalid overloads from compiling ✔️ Write safer and more expressive generic code ⚙️ Bonus insight from the video: You’ll see how SFINAE works step by step by evolving this basic function: 1️⃣ Basic function behavior Understand the baseline implementation 2️⃣ Applying SFINAE Control when the function is enabled 3️⃣ Safer templates Restrict usage to valid type combinations 🎯 Key takeaway: SFINAE helps you guide the compiler instead of fighting it. It’s a foundational technique for mastering modern C++ templates. 🎥 Watch the video: https://lnkd.in/d7zPHDzb 📚 Full playlist: https://lnkd.in/dDNVWvVC #cpp #moderncpp #programming #softwareengineering #templates #cleancode

🔹 Type Deduction in C++ (auto, decltype) This short video is part of my "C++ Programming Topics" series 👇 And also included in my broader learning playlist. 💡 The problem: Many developers either over-specify types or rely on guesswork when writing modern C++ code. This can lead to: -Verbose and harder-to-read code -Subtle bugs when types are not what you expect -Reduced flexibility when refactoring ❌ 📌 This is where type deduction becomes powerful: 👉 Let the compiler infer the correct type safely and efficiently. 💡 The solution: Using modern C++ features like auto, decltype, and template deduction: ✔️ Write cleaner and more concise code ✔️ Reduce redundancy ✔️ Let the compiler handle complexity ⚙️ Bonus insight from the video: You’ll see how type deduction works in different scenarios: 1️⃣ auto Great for simplifying variable declarations Improves readability when types are obvious 2️⃣ decltype Useful when you need the exact type of an expression Helps in advanced template and generic programming 3️⃣ Template Type Deduction The core concept behind generic programming Enables flexible and reusable code 🎯 Key takeaway: Don’t fight the compiler—use it. Modern C++ gives you tools to write cleaner, safer, and more maintainable code. 🎥 Watch the video: https://lnkd.in/dZSDe2Pi 📚 Full playlist: https://lnkd.in/dDNVWvVC 📚 Source code, examples, and notes: https://lnkd.in/dy2Kp-4f #cpp #moderncpp #programming #softwareengineering #templates #cleancode

🔹 Part 1: C++ Concepts vs SFINAE (Practical Guide) This short video is part of my "C++ Programming Topics" series 👇 And also included in my broader C++ templates playlist. 💡 The problem: SFINAE is powerful—but it often leads to complex, hard-to-read template code. This can cause: -Cryptic compiler errors -Reduced code clarity -Higher learning curve for maintainers ❌ 📌 This is where C++20 Concepts shine: 👉 They provide a clean and expressive way to constrain templates. 💡 What you’ll learn in this video: ⚙️ Step-by-step evolution from SFINAE to Concepts: 1️⃣ Using enable_if in template parameters A cleaner alternative than putting it in the return type 2️⃣ Constraining a template class (Wrapper) Allow only integral types using SFINAE 3️⃣ Generic sum function Handle different types and control the return type 4️⃣ Concepts vs SFINAE Clear comparison in readability and maintainability 5️⃣ Writing your own concept Define a requirement for types that support add and sub 6️⃣ Combining Concepts with type_traits Reuse existing utilities for powerful constraints 🎯 Key takeaway: Concepts don’t replace SFINAE—they simplify it. Use Concepts when readability matters, and SFINAE when you need lower-level control. 🎥 Watch the video: https://lnkd.in/dpiQNQcF 📚 Full playlist: https://lnkd.in/dDNVWvVC #cpp #moderncpp #programming #softwareengineering #templates #concepts #metaprogramming #cleancode

How Two Classes Communicate in Modern C++ (Composition, References/Pointers, Interfaces, and Friend Class):- In modern C++, classes do not work alone. They interact with each other to share responsibilities and build complete applications. This interaction can be designed in different ways, such as composition, references or pointers, interfaces, and friend class. Understanding these communication methods is important because the right choice leads to cleaner, safer, and more maintainable code. Introduction How Two Classes Communicate in Modern C++ Composition, References/Pointers, Interfaces, and Friend Class In modern C++, software is built by dividing a problem into multiple classes, where each class has its own responsibility. But a single class usually cannot solve everything alone. To build real applications, classes must communicate with each other so they can share data, request services, and work together to complete a task. This is why understanding how two classes communicate is an important part of object-oriented programming (OOP) and software design. What does it mean? When we say two classes communicate, we mean: one class uses another class one class owns another class one class depends on another class one class implements a contract for another class one class may even get special access to another class In C++, this communication can happen in different ways, such as: Composition References / Pointers Interfaces Friend class Each method represents a different relationship between classes. Why is this important? Understanding class communication is important because it directly affects: code readability maintainability reusability testability scalability If classes communicate in the wrong way: code becomes tightly coupled changes become difficult debugging becomes harder reuse becomes limited If classes communicate in the right way: the design becomes cleaner the system becomes easier to extend testing and maintenance become simpler So, choosing the correct relationship between classes is a key part of writing good modern C++ code.  #ModernCpp #CppProgramming #OOP #SoftwareDesign #CleanCode #SoftwareEngineering #Programming

🔹 Part 2: C++20 Concepts (Advanced Usage & Clean Syntax) This short video is part of my "C++ Programming Topics" series 👇 And also included in my broader C++ templates playlist. 💡 The problem: Even with basic concepts, many developers still struggle to write clean and scalable constraints. This can lead to: -Overly complex template conditions -Poor readability when combining multiple constraints -Missing out on the full power of C++20 ❌ 📌 This is where advanced Concepts usage makes a difference: 👉 Writing expressive, composable, and clean constraints. 💡 What you’ll explore in this part: ⚙️ Deeper dive into Concepts: 1️⃣ Using the Concepts library Leverage standard concepts directly instead of reinventing constraints 2️⃣ Multiple constraints Combine type_traits and Concepts for precise control over types 3️⃣ Constrained template classes (Wrapper) Write cleaner and safer class templates with clear requirements 4️⃣ C++20 syntactic sugar Simplify template syntax and make intent more readable 🎯 Key takeaway: Concepts are not just about constraints—they’re about clarity. Modern C++ lets you express what you mean instead of how to enforce it. 🎥 Watch the video: https://lnkd.in/dpiQNQcF 📚 Full playlist: https://lnkd.in/dDNVWvVC #cpp #moderncpp #programming #softwareengineering #templates #concepts #metaprogramming #cleancode

-->Unlocking the "Mother of All Languages": C Programming Ever wondered how your favorite operating system, gaming engine, or smart device actually works? Most roads lead back to C. Created in the 1970s, C is often called the "Mother of All Languages" because it’s the foundation for almost everything we use today. If you’re just starting your coding journey, here’s a beginner-friendly breakdown: --> The Purpose: Why C? C is like the chassis of a car. While Python or JavaScript might be the sleek paint and comfortable seats, C is the powerful engine and frame that makes everything move. It’s "low-level," meaning it talks very closely to the computer’s hardware, making it incredibly fast and efficient. --> The Structure: A Simple "Hello World" Every C program follows a specific blueprint. Think of it like writing a formal letter: >>The Header (#include <stdio.h>): This is like grabbing your stationery. It tells the computer you need standard tools to handle text. >>The Main Function (int main()): This is the "Front Door." No matter how big the house is, the computer always enters here first. >>The Body { ... }: This is where the action happens—the actual instructions you want to execute. --> Input & Output: The Real-World Connection Imagine a Vending Machine: >>Output (printf): This is the machine’s display screen telling you "Select a snack." In C, printf "prints" information onto your screen. >>Input (scanf): This is the keypad. When you type "A1," the machine "scans" your input and processes it. In C, scanf is how your program listens to the user. Why learn C in 2026? It teaches you how computers actually think. Once you master the logic of C, learning any other language feels like a breeze. Are you currently learning C or thinking about starting? Let’s discuss in the comments. #CProgramming #CodingNewbie #TechEducation #SoftwareEngineering #LearnToCode

C++ might be the most complex programming language today. It supports multiple paradigms, offers a large std library, and has evolved a lot over decades. It has many ways of doing things. The result is a language that’s flexible, but hard to master. Wat is "Good C++"? Define it for me. Two experienced developers can write completely different C++, different styles, tools, considerations, depending on context like performance, libraries, or project needs, or even personal taste. Do you see this also in C++, so many valid ways to solve the same problem? Do you ever feel overwhelmed trying to write or understand "good C++"? What does "good C++" even mean to you?

Generic programming in C is not missing. It’s just not handed to you. You can fake it with void*, abuse the preprocessor, or use template-style macros. Or you can generate real code and debug it like normal C. I wrote a breakdown of all approaches and why I prefer code generation. https://lnkd.in/dAGvr-XX

I found this book outstanding — the gradual introduction to functional programming in C++ is very well done, and the practical examples make the ideas truly click. It’s a great resource for anyone looking to deepen their understanding of modern C++ techniques.

Built a custom string handling class in C++ from scratch — without using std::string. This project focuses on: • Dynamic memory management using new[] and delete[] • Implementation of the Rule of Three (Destructor, Copy Constructor, Copy Assignment) • Manual string manipulation algorithms (reverse, case conversion, word counting) • Operator overloading for intuitive usage (+, +=, [], (), comparison operators) The goal was to deeply understand how strings work internally rather than relying on built-in abstractions. A great exercise in mastering memory management, object-oriented programming, and low-level string operations in C++. #cpp #programming #softwareengineering #oop #learning #developers
