D Programming Fundamentals: Structs and Card Deck Manipulation

Working with structured data is a core skill for any developer, and the D programming language offers uniquely powerful tools to make your code both safe and efficient. This text-based course guides you through modeling real-world systems, using a playable card deck as a practical learning model. You will transition from basic syntax to structuring robust applications in D. By building a card deck simulation, you will master custom data types, enforce code reliability, and manipulate collections with confidence. What you will learn: Understand the fundamentals of D structs, memory layout, and member functions; Implement robust contract programming with pre-conditions and post-conditions to prevent bugs; Manipulate collections using D's native ranges and standard library shuffling algorithms; Write clean, self-documenting code using modern D idioms and built-in unit testing; Model complex state transitions and card behaviors using clean structures without class overhead. The course begins with foundational D syntax and struct definitions before progressing to contract programming and advanced range manipulation. You will read structured explanations, analyze clear code snippets, and practice with written exercises. This course is designed for beginner programmers or developers new to the D language, with no prior experience with D required. Start reading today to unlock the power of D's elegant type system.
