Walls And Mirrors

	Walls And Mirrors ''Walls And Mirrors'' is a computer science textbook, for undergraduates taking a second computer science course (typically on the subject of data structures and algorithms), originally written by Paul Helman and Robert Veroff. The book attempts to strike a balance between being too mathematically rigorous and formal, and being so informal, practical, and hands-on that computer science theory is not taught. The "walls" of the title refer to the abstract data type (ADT) which has a wall between its public interface and private implementation. Early languages like Pascal did not build this wall very high; later languages like Modula-2 did create a much stronger wall between the two; and object-oriented languages such as C++ and Java implement walls using the Class (computer science), class concept. The "mirrors" of the title refer to recursion. The idea is of looking at a reflection in two mirrors placed in opposition to one another, so a repeated image is reflected smaller and smal ...

picture info	Computer Science Computer science is the study of computation, automation, and information. Computer science spans theoretical disciplines (such as algorithms, theory of computation, information theory, and automation) to Applied science, practical disciplines (including the design and implementation of Computer architecture, hardware and Computer programming, software). Computer science is generally considered an area of research, academic research and distinct from computer programming. Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and for preventing Vulnerability (computing), security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Progr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Robert Veroff The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be used ...
