Thursday September 15, 1994

Assigned Reading: 2.2 - 2.3

Handouts (available on-line): none

Topics Covered:

• Announced some corrections from previous class. The problem is that some people did not have a bin directory and copied the cc201 file to their accounts as ~/bin. This caused problems.
• Discussed using World Wide Web to distribute course information.
• Review: an example of a program that uses integer, floating point and string variables. Program and sample run.
• A program that converts centimeters to feet and inches. Program and sample run.
• Discussed variable types integers, floating point numbers, characters, Boolean values and strings.
  • Examples of integer constants.
  • Examples of floating point constants.
  • Examples of other constants.
• A program that uses all these types and sample run.
• Discussed what is an "integer expression".
• Discussed operator precedence and associativity (important). Multiplication and division have higher precedence than addition and subtraction. These four operators also associate left to right. Assignment is an operator too; it associates right to left.
