CSC 161 Grinnell College Fall, 2011 Imperative Problem Solving and Data Structures

# Semester Outline for CSC 161

Module Dates Overall Purpose Summary and Main Topics Examples Lab Exercises Project Theme
0 (module details) Friday, August 26 — Tuesday, September 6 Introduction: Play a song
This module helps CSC161 students to gain familiarity with foundational concepts of C programming, the Scribbler robot, and the Linux terminal.
Basics of Linux and C
• basic Linux
• introduction to using the terminal
• elements of a C program, including variables and primitive types
• basic Scribbler actions (beeping)
• Pirates of the Caribbean
• Spirit Song
Program a song
1 (module details) Wednesday, September 7 — Friday, September 16 Motion (+song, motion)
This module introduces and explores the possibilities that are offered by loops and conditionals. These capabilities are applied to controlling a robot that creates sounds and moves simultaneously.
Control structures
• conditional statements
• loops (e.g. initialization, iteration, condition testing, loop body, for, while)
• Scribbler motion
• Dance
• Ice cream truck
• Types and variables (with casting)
• Conditionals, Scribbler motion
• Loops
• Loops and Scribbler 2 motion
Make the robot dance and sing
Monday, September 23 Hour Test 1
2 (module details) Monday, September 19 — Wednesday, September 28 Motion and sensors
This module expands the CSC161 students' working knowledge of C language, improves problem solving and creativity, and creates an introduction to more complex programming.
functions and arrays
• one-dimensional arrays,
• writing functions,
• testing programs and functions,
• Scribbler 2 motion and sensors
• Avoid object
• Move until a wall and turn right
• Braitenberg machine: Alive
• 1-dimensional arrays
• testing:
• functions and parameters
• values, addresses, and the & operator (2 labs)

(details)
Friday, September 30 — Tuesday, October 4 Data representation Representation of numbers
• non-negative binary integers
• sign-magnitude, ones- and twos- complement notation
• floating point representations
• integer representation
• floating-point representation
3 (module details) Wednesday, October 5 — Monday, October 24 Deepen understanding of imperative problem solving and C
The purpose of this module is to deepen understanding of the C language and smoothly integrate previous experience in the course into the larger framework of programming in C.
Arrays
• characters
• strings
• input/output
• forthcoming
• characters and strings
• Input/output
Robot follows typed commands
Wednesday, October 12 Hour Test 2
4 (module details) Tuesday, October 25 — Friday, November 4 Image Processing
The purpose of this module is to introduce the customizable nature of self-written programs by using structs and 2-dimensional arrays.
Structured data
• structs
• 2-dimensional arrays
• change pixel (shell, full program)
• transform pictures
• transform a pixel
• transform pixels in a picture
• sort pixels in a picture
Transform a Picture
5 (module details) Wednesday, November 2 — Monday, November 14 Music Composition
This module introduces dynamic data structures (with pointers and linked lists) as a means to store lines of music that evolve through the composition process.
Dynamic data storage
• pointers
• insert theme into canon/fugue
• pointers: create/return array, populate with sensor data
Music composition --- insertion of series of notes periodically into song tune
6 (module details) Tuesday, November 15 — Monday, November 28 Storage/retrieval Patterns
This module increases familiarity with programming in C, integrates the Scribbler 2's sensors into the curriculum, and continues to practice previously-introduced concepts
The purpose of this module is to clarify previously introduced concepts, such as
• more pointers and linked lists
• queues
• stacks
• Bash scripts
• Transform image in various ways
• stacks
• queues
• Bash scripts (for testing)
Do something interesting with pictures or travel in a maze
Monday, November 21 Hour Test 3
7 (module details) Tuesday, November 29 — Friday, December 9 Integrated Robotics
This module integrates and reviews material that has been presented through the semester, with a particular emphasis on C programming concepts and full usage of the Scribbler robot.
• Files
• Command-line arguments
• use robot with command-line actions and with log file
• reading and writing with files
• files for include, separate compilation, separate linking
• command-line arguments
Robot motion with logging
