CSC 161 Module 3: Working with Characters, Strings, and I/O

Introduction

This module introduces CSC 161 students to writing dynamic programs that can take input and follow commands based on input, including

  1. characters
  2. strings,
  3. input and output.

Project: Robot Follows Typed Commands

Working in pairs, students should develop a program that includes these elements:

Together with the program, a student pair must write a paragraph that describes what tests are needed to demonstrate the program is working correctly. That is, what should a tester do to demonstrate the program works? Also, the student pair must present a sequence of steps that the tester should do to carry out the test plan. (E.g., what should be typed in a terminal window, including the details of the compile, link, and run steps?)

Command Requirements

Grading

This project will be worth 25 points, based on the following rubric:

Note

This project is planned for use as the base of a later project, so you will want to document your code well now — in anticipation of later activities.
