D Programming Fundamentals: Pointers, Delegates, and Lambdas

To write high-performance and flexible applications in D, you must understand how to treat functions as first-class citizens. This course teaches you the core mechanisms for dynamic function invocation, allowing you to create powerful callback systems, event handlers, and highly modular code structures. You will gain control over program flow by mastering function pointers, delegates, and anonymous functions. What you'll learn: * Understand the underlying mechanics and syntax of function pointers in D for direct function referencing. * Differentiate between function pointers and delegates, and apply delegates effectively for object-oriented callbacks and closures. * Implement lambda expressions and anonymous functions to create concise, inline logic without defining separate named functions. * Practice using closures to capture and access variables from the surrounding scope securely. * Apply these techniques to structure modular code and integrate basic unit testing patterns using D's built-in features. We begin by defining the core terminology and mechanics of function referencing, moving step-by-step through practical examples demonstrating pointers, delegates, and lambdas in action. This course is designed for beginners who are already familiar with basic D syntax and want to deepen their understanding of advanced control flow and programming paradigms.
