Programming Assignment #2
CS 163: Data Structures
Spring 2011
Problem Statement:
The goal of program #2 is to gain experience with stacks and queues.
We have been hired by CS Airways. They would like to use the process of stacks and
queues to automate the

Scope:
When beginning with this project, the first thing to keep in mind is that we only
have approximately 2 weeks to complete each assignment. Therefore, it is critical
that you focus on a limited scope.

Data Abstraction
Given what we talked about last time, we need
to step through an example of an abstract data
type using
classes,
constructors,
member functions,
data hiding,
distinguishing the difference between

CS163: Data Structures
Overview:
Hash tables are very useful in situations where an individual wants to quickly find
their data by the value or search key. You could think of them as similar to an
array, except the client program
