CS141: Topics for Jan 27, 29, & 31, 2014

• Labs
  • Continue Lab 1: Introduction to Processing. This lab is due Wed before class.
  • Begin Lab 2: Repetition and Looping.

• More on functions and scope.

• Practice:

  • Loop Practice problems (pdf)
  • Loop Practice problem solutions (pdf): Before looking at these try to figure them out on your own. You can also try running the code in Processing.
  • Variables Practice problems (pdf)
  • Conditionals Practice problems (pdf) (txt code)

• Review from last week:

  • Arithmetic (+, -, *, /, %) and the assignment statement (=)
  • function and parameters, setup() function
  • for-loops, nested for-loops

• Programming Terminology and Concepts for this Week

  • Looping through time using setup() and draw()
  • Scope of variables
  • Making Choices - Conditional expressions
    • boolean variable
    • Conditional expression
    • Comparison operators: <, >, <=, >=, !=
    • "if" statement and the "if-else" statement
    • boolean operator: AND (&&), OR (||), NOT (!)
    • relational operator
    • In Processing reference - look under Control:
      • relational Operators
      • Conditional
      • Logical Operators
  • Random numbers
    • In Processing reference - look under Math, random
    • random, randomSeed

• General References on Design:

  • Visual Design
