Outline for June 3, 2002

Handouts:Sample Finall

Reading: none

1.	Greetings and felicitations!

2.	Static debugging 

a.	using printf to print variable values; mention %p (prints pointer value, usually as a hex integer)

b.	using printf to print where you are (ie, on function entry printf("in function\n");

c.	#ifdef DEBUG - #endif around the printfs so you can leave them in the source if you need them again

d.	assert(x) macro: assert(0 <= i && i <= n) causes program to exit with error message if (0 <= I && I <= n) is 
false; must include <assert.h>.  To delete, say #define NDEBUG and they will not be in the compiled code.

3.	Dynamic debugging

a.	debugging tool instruments executable program so it can be stopped, examined, altered, and continued inter-
actively

b.	go through the handout

c.	mention the "where" command which shows you the program stack
