• Continue to work on Lab 1: Introduction to Processing.

  • This lab is due Wed at midnight.
  • In class, discuss how to submit assignments on WISE.

• Begin Lab 2: Repetition, Looping, and Making Choices .

• Programming Elements for this Week

  • See Readings in Lab 2
  • Expressions (value) vs Statements (complete sentences, end with semi-colon)
  • Variables
    • Variable Declaration
    • Variable Assignment
    • In Processing reference - look under Data, primitive
    • Examples: int, float, double, boolean
  • Arithmetic (+, -, *, /, %) and the assignment statement (=)
  • Loops:
    • In Processing reference - look under Control, for, while

  • Making Choices - Conditional expressions
    • "if" statement and the "if-else" statement
    • Comparison operators: <, >, <=, >=, !=
    • boolean operators: AND (&&), OR (||), NOT (!)
    • In Processing reference - look under Control, relational Operators
  • Random numbers
    • In Processing reference - look under Math, random
    • random, randomSeed
  • Other: Interaction - setup/draw, map function

• Don't forget Design Elements and Design Principles.

• Relationship between design and programming
