Objectives

Mastery of:

•Using basic C++ control structures and statements, the basic classes Boolean, Character, Integer, Real, Text, Character_IStream, Character_OStream, and related RESOLVE/C++ principles for clients, to write simple main programs and layered implementations of operations;

Familiarity with:

•Using the computing environment (operating system, tools, language system, etc.) to complete lab assignments and to communicate electronically with others;

•Using the GUI_Catalog, Id_Name_Table, Least_Cost_Path_Machine, and Natural_Number classes to write simple main programs and layered implementations of operations;

•Using simple recursion to write layered implementations of operations;

•Using simple predicate calculus assertions involving mathematical integer, string, and tuple models to understand and reason about an operation's behavior;

•Using simple techniques to test layered implementations of operations, including developing and carrying out simple specification-based test plans;

•Using simple techniques to debug layered implementations of operations;

Exposure to:

•Writing simple predicate calculus assertions involving mathematical integer, string, and tuple models to describe the intended behavior of an operation;

•Using induction arguments to establish the correctness of recursive implementations of operations;

•Using simple loop specifications to reason about loop behavior.
