Part 63 Taming Dragons with Stroustrup’s Blade - Using Function Pointers as Callback in C++

In this episode of “Taming Dragons with Stroustrup’s Blade”, we explore the concept of callback functions in C++, one of the most powerful design patterns for modular and flexible programming. You’ll learn how callbacks work through function pointers, how to integrate them into encryption and decryption systems, and how they enable decoupled and reusable interfaces in real-world applications. ⏰ Timestamps: 00:00 ▶️ Introduction to Callback Functions — What callbacks are, why they exist, and how they improve modularity and event-driven designs. 01:30 ▶️ Real-World Applications of Callbacks — Understanding how callbacks are used in systems like GUIs, async operations, and signal handling. 02:50 ▶️ Types of Callback Functions — Exploring free function callbacks, static member callbacks, and functor/lambda-based callbacks in C++. 04:50 ▶️ Implementing Encoder/Decoder with Function Pointers — Using callbacks to dynamically link encoding and decoding operations via function pointers. 05:20 ▶️ Designing Main Interface for Encryption/Decryption Streams — Creating a central function that routes string data through callback-based processing pipelines. 07:20 ▶️ Implementing Encryption and Decryption Functions — Writing modular encode/decode logic that can be swapped or chained via callback hooks. 15:15 ▶️ Using Callback Functions for Message Encryption and Decryption — Demonstrating the full callback mechanism in action, processing text dynamically through encryption and decryption routines. 📌 What You'll Learn: • The concept and mechanics of callback functions in C++ • How function pointers and lambdas serve as flexible callback mechanisms • Designing extensible systems using callback-based function architecture • Real-world example of callback integration in an encryption/decryption module • How callbacks enable runtime customization and modular programming 🛠 Concepts Covered: • Function pointers and callback design in C++ • Static vs dynamic function binding • Modular encoder/decoder architecture • std::function and lambda expressions as callbacks • Applying callbacks in cryptographic or streaming pipelines 📢 Community & Resources: 🌐 Website: https://acql.ir 📸 Instagram: @aiooo_cql 📢 Telegram: @aioooir 🐦 Twitter: @aioooir 💻 GitHub: https://github.com/aiooord 🧪 Challenge for Viewers: Create a C++ program that: • Defines two encryption algorithms (e.g., XOR and Caesar cipher). • Implements a single processing function that accepts a callback pointer for either algorithm. • Reads input text, applies encryption/decryption via the callback, and outputs the result. • Experiment by replacing the callback with a lambda to see how flexible function binding can be.
