CS 138 Introduction to Data Abstraction and Implementation

Objectives

This course introduces software engineering students to elementary data structures, and to the functional programming paradigm.

Intended Audience

Software Engineering undergraduates who have taken SE 1A. It is assumed that students have experience programming in an imperative language such as C or C++.

    Functional programming paradigm. Scheme grammar and syntax, functions, predicates, expressions, values, recursion on integers.

    Structured data (6 hours)

    Scheme memory model, lists, recursion on lists, mutual recursive data definitions, trees.

    Functional Abstraction (3 hours)

    Design recipes for recursive algorithms.

    Mutation and encapsulation (1.5 hours)

    Mutation, sequencing of statements, state encapsulation, structures.

    Abstract Data Types and classes (3 hours)

    Abstract data types (ADTs) in C++: interfaces vs. implementation, access specification, classes, objects, object instantiation.

    List, Stack, and Queue ADTs (6 hours)

    Implementation in C++ using arrays and dynamic storage, implementation in Scheme, space and time complexity of operations, applications (nested procedure calls, parsing of arithmetic expressions).

    Tree ADT (6 hours)

    Trees and binary trees, binary search trees, preorder and postorer traversals, space and time complexity of operations, applications (dictionaries).
