Part 67 Taming Dragons with Stroustrup’s Blade - Generic Coding | Templates and Compile Resolution

In this episode of “Taming Dragons with Stroustrup’s Blade”, we explore Generic Programming in C++ — the foundation of templates, compile-time resolution, and type-independent design. You’ll learn how C++ templates enable powerful abstraction, type safety, and code reuse without runtime cost. This session dives deep into class templates, linker errors, and best practices for separating declarations and definitions across header and source files. ⏰ Timestamps: 00:00 ▶️ Introduction to Generic Programming with C++ — Understanding the philosophy behind generic programming and how templates achieve compile-time polymorphism. 01:40 ▶️ Templates and Compile-Time Resolution — Exploring how templates are instantiated, how the compiler generates type-specific code, and why templates improve performance. 02:40 ▶️ Implementing a Class with a Template — Building a simple class template to handle multiple data types with a single definition. 03:55 ▶️ Declaring Template Classes in Header Files — Explaining why template declarations typically reside in header files and the implications for compilation. 05:45 ▶️ Defining Template Classes in CPP Files — Demonstrating how separating template definitions into source files can lead to linker issues. 10:00 ▶️ Understanding “Unresolved External Symbol” Errors — Analyzing common linker errors when templates are improperly separated between .h and .cpp files. 16:00 ▶️ Combining CPP and Header for Linker Resolution — Practical strategies to resolve linker problems using header-only templates, .tpp inclusion, or explicit instantiation. 📌 What You'll Learn: • How C++ templates enable generic and reusable code • Why template instantiation happens at compile time • How to correctly organize template code across headers and source files • What causes linker errors in template projects and how to fix them • When to use explicit instantiation vs header-only design 🛠 Concepts Covered: • Template declaration and definition rules • Compile-time polymorphism and instantiation • Linker error diagnostics and resolution techniques • Header-only library patterns • Template best practices in modern C++ 📢 Community & Resources: 🌐 Website: https://acql.ir 📸 Instagram: @aiooo_cql 📢 Telegram: @aioooir 🐦 Twitter: @aioooir 💻 GitHub: https://github.com/aiooord 🧪 Challenge for Viewers: Write a small C++ program that: • Defines a class template for storing and retrieving values of various types. • Separates declaration and definition across .h and .cpp files. • Experiments with explicit template instantiation for int, double, and std::string. • Investigates what happens when definitions are omitted and resolves linker errors.
