Algorithms + Data Structures = Programs is a 1976 book written by Niklaus Wirth covering some of the fundamental topics of system engineering, computer programming, particularly that algorithms and data structures are inherently related. For example, if one has a sorted list one will use a search algorithm optimal for sorted lists. The book is one of the most influential computer science books of its time and, like Wirth's other work, has been used extensively in education. The Turbo Pascal compiler written by Anders Hejlsberg was largely inspired by the Tiny Pascal compiler in Niklaus Wirth's book.
