CS 138 Introduction to Data Abstraction and Implementation


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++.
