1. Lecture 13: Character Strings, Pointers to Pointers, Command Line Arguments Homework: Read Chapter 12 of Barclay

2. Lecture 13: Outline Character strings. String manipulation functions. Pointers to Pointers. Double indirection Command Line Arguments. Process command line for programs.

3. Character Strings A sequence of character constants such as �This is a string !�. Each character of the string is a character constant in a consecutive memory block. Representation in memory:
