Part 64 Taming Dragons with Stroustrup’s Blade - Flexible Design of Callbacks with std::function

In this advanced episode of “Taming Dragons with Stroustrup’s Blade”, we extend our exploration of callback functions in C++, moving from raw function pointers to the modern and type-safe std::function. You’ll learn how to define flexible callback signatures, integrate them into cryptographic pipelines, and enhance encryption/decryption algorithms with multiple interchangeable implementations. ⏰ Timestamps: 00:00 ▶️ Overview of Callback Functions — Revisiting the callback concept and its importance in modular, event-driven program design. 01:00 ▶️ Using std::function for Callback Signatures — Introducing std::function as a safer, more flexible alternative to raw function pointers for defining callback APIs. 03:15 ▶️ Improving the Decryption Algorithm — Refining the existing cryptographic callback logic to improve accuracy, maintainability, and code safety. 05:50 ▶️ Implementing the Second Encoder Variation — Building a new version of the encoder function and dynamically linking it using the callback system. 06:20 ▶️ Implementing the Second Decoder Variation — Completing the two-way pipeline by developing an alternate decoder and testing interoperability with the main encryption interface. 📌 What You'll Learn: • How to implement callback functions using std::function • The advantages of type-safe callback systems over raw pointers • How to plug and play different algorithms through callback design • Improving cryptographic systems with modular function interfaces • Applying runtime polymorphism through functional design 🛠 Concepts Covered: • std::function and function signature abstraction • Function pointer modernization in C++17 and C++20 • Callback chaining and runtime function replacement • Modular encoder/decoder architecture with interchangeable logic • Functional programming principles in C++ 📢 Community & Resources: 🌐 Website: https://acql.ir 📸 Instagram: @aiooo_cql 📢 Telegram: @aioooir 🐦 Twitter: @aioooir 💻 GitHub: https://github.com/aiooord 🧪 Challenge for Viewers: Write a C++ program that: • Uses std::function std::string(const std::string&) as a callback signature. • Implements two encryption algorithms (e.g., XOR and Shift Cipher). • Dynamically switches between them during runtime using user input. • Tests the entire encryption/decryption flow with both variations.
