About this course

In the D programming language, a solid grasp of the distinctions between classes and structs is fundamental for writing performant and reliable code. Choosing the correct data structure impacts everything from memory management to object-oriented design patterns. This course will guide you through the essential differences, enabling you to make informed design decisions and leverage D's powerful type system effectively. What you'll learn: * Understand the fundamental distinctions between D classes as reference types and structs as value types. * Learn how memory allocation (heap versus stack) and ownership patterns differ for each data structure. * Apply core object-oriented principles like inheritance and polymorphism when designing with D classes. * Grasp the concept of nullability for class instances and its absence for structs, including safe handling patterns. * Practice choosing the optimal type (class or struct) for various programming scenarios to enhance code efficiency and maintainability. * Explore modern D idioms for ensuring type safety and leveraging immutability effectively with both classes and structs. The course begins by establishing foundational concepts of types and memory, then systematically explores the unique characteristics and use cases for D classes and structs. You will then apply this knowledge to practical programming considerations and modern D best practices. This course is designed for beginner D programmers with no prior experience with object-oriented programming concepts or advanced type systems. Begin your journey to mastering D's powerful type system today.
