About this course

Working with text in modern programming requires a deep understanding of how strings are stored, measured, and compared. In the D programming language, handling strings efficiently means mastering Unicode representations, length calculations, and lexicographic comparisons. This course provides a solid foundation in D's string mechanics, taking you from basic character literals to advanced multi-byte string operations. You will gain the confidence to manipulate text safely, avoid common encoding pitfalls, and write performance-oriented D code. What you'll learn: 1. Understand the core differences between string, wstring, and dstring types in D. 2. Manage Unicode literals and multi-byte character representations accurately. 3. Calculate string length correctly while accounting for code units versus code points. 4. Compare strings lexicographically using D's native operators and standard library functions. 5. Concatenate strings efficiently using modern memory-safe practices. 6. Practice text manipulation using standard library modules like std.string and std.uni. The course begins with foundational concepts of how D stores characters and strings in memory. You will then progress through practical text operations, exploring length nuances, concatenation, and lexicographic ordering through clear written explanations and structured code examples. This course is designed for beginners to the D programming language and developers looking to solidify their understanding of low-level string handling. No prior experience with D is required. Start reading today to master string manipulation in D.
