• Programming
  • review of programming basics from last time
  • list functions
  • the conditional function: if
  • using conditionals and recursion to program repetition
• In-class exercise. Starting with the TenCones Mead example, take a non-primitive object from a previous class example or from your own work and place it into the scene using a function similar to addCones in some appropriate pattern.

  Submit by demonstrating in class, or by email as "Lecture 16 in-class exercise" for 10 lecture assignment points.

Lecture Assignment 16

Due at the start of class, Tuesday, March 26.

Please submit answers to these questions either as a hard copy (typeset or handwritten are OK) or by email to terescoj AT strose.edu by the start of class. Please use a clear subject line when submitting by email (e.g., CSC 112 Lecture Assignment 16, Joe Student). We will discuss these questions at the start of class, so no late submissions are accepted.
