CSC 161 Module to Introduce Conditionals, Loops, and Scribbler 2 Motion


This module introduces CSC 161 students to several fundamental elements of programming in C, including:

  1. using conditional statements (e.g., if, switch),
  2. using loops (e.g., initialization, iteration, condition testing, loop body with for, while), and
  3. introducing motion with the Scribbler 2 robot.

Project Options

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 steps are needed to demonstrate the program is working correctly (this can be pseudocode).

Project Submission

As with Project 000, submission of your project should come in two parts:

Some additional guidelines follow:
