Tuesday September 19, 1995

Assigned Reading: 3.1 - 3.3

Handouts (available on-line): Project 1

Topics Covered:

• We examined a for loop that prints out the multiples of 3 from 3 through 30. Program and sample run.
• While loops, several ways of adding a list of numbers until the user enters a zero:
  • using a break statement. Program and sample run.
  • without using a break statement. Program and sample run.
  • using side effects (bad style) Program and sample run.
• We discussed several indentation styles.
• Some simple programs using an if statement.
  Testing an input integer to check if it is even or odd: Program and sample run. Testing an input integer to check if it is positive, negative or zero: Program and sample run.
• A very common bug is using one = instead of == to test for equality in an if statement. A seemingly correct program can produce strange results. Program and sample run.
• Discussed Project 1.
