Handouts: More Sample C Programs
Reading: Johnsonbaugh & Kalin pp. 230-237, 305-329

1. Greetings and felicitations!
1. Homework 2 to be handed out on Monday, will be due on April 29
2. copy1.c
1. strings (NUL-terminated arrays)
2. printing strings
3. copy2.c
1. definition of pointer; address of variables (&), dereferencing of pointer (*)
2. how it is used
3. pointer arithmetic (in the printf)
4. swaps.c
1. pointers and parameter lists
2. pointers and var paramaters
5. paa.c
1. str1copy: condition on for, explicit comparison
2. str1copy: condition on for, implicit comparison
3. str3cpy: condition on for, implicit comparison from assignment
4. str4cpy: pure pointers
6. fileio.c
1. like program 5 from first handout, but driven by files not standard input
2. show technique for developing this (program becomes function, add file I/O driver)
3. go through file manipulation functions
