Notes from 9/2

• syntax of the three kinds of loops
• Loops need:
  • A control variable.
  • The control variable initialized.
  • A test for an exit condition.
  • Something that moves the loop closer to the exit condition.
• i++, ++i
• i += 1
• Computer lab => experiment
• Scientific method
  • Form a hypothesis
  • make predictions based on the hypothesis
  • test those predictions with experimentation
  • repeat as needed
• if (const == var) is better than if (var == const)
• less code means
  • Less chance of creating an error
  • Easier job of finding errors
• Compile often.
