Algorithms + Data Structures = Programs

Algorithms + Data Structures = Programs is a foundational 1976 computer science text by Niklaus Wirth that establishes the fundamental relationship between algorithms and data structures in programming. The book presents core concepts through practical examples and implementations in Pascal, covering topics from basic data structures to sorting and recursive algorithms. The text is structured in five main chapters that build progressively from fundamental concepts to more complex implementations, including compiler design and language structures. Each concept is explained through concrete programming examples and exercises that demonstrate the practical application of theoretical principles. The book features clear explanations of how data organization directly influences algorithm choice and program efficiency, supported by detailed Pascal code examples and syntax diagrams in the appendices. The included Tiny Pascal compiler implementation served as inspiration for later developments in programming language design. This work stands as a cornerstone of computer science education, presenting a systematic approach to program construction that emphasizes the inherent connection between data organization and algorithmic solutions. Its influence extends beyond its era, establishing principles that remain relevant to modern software development.

Most readers value this book as a structured introduction to core programming concepts, with many highlighting its clear progression from simple to complex topics. Students appreciate the Pascal code examples and systematic approach to problem-solving.
