Lecture 8: Data Representation
3.8-3.11 of textbook (CS:APP)
Sec 7 of x86-64 textbook supplement

Sample code used in lecture to illustrate
arrays and pointers, structs, and unions

sum.c -- sum elements of an array
point.c -- point example for structs
list.c -- linked list example for structs
exp.c -- expression examples for unions

Compiled for x86-64
sum.c is compiled two ways, to see different optimization
levels; sum1.s uses lower level of optimization than sum2.s
