UMBC CMSC201, Computer Science I, Fall 1994 Sections 0101, 0102 and Honors

Tuesday November 29, 1994

Assigned Reading: 13.1 - 13.2

Handouts (available on-line): none

Topics Covered:

• Discussion of self-reference and what it has to do with pointers.
• Explained the pointer operators & (address of) and * (de-reference). Also explained how to declare pointer variables. Worked through some examples on the whiteboard.
• We looked at a simple program that uses pointers. Program and sample run.
• A program that uses pointers incorrectly. You are not allowed to assign integer expressions or integer constants (except for zero) to an integer pointer. You are also not allowed to assign the address of a double variable to an integer pointer. The compiler will complain about syntax errors in these situations.
