Agenda what ?s finish jmalloc what happens when TODO Optional: check out the section of the C FAQ on memory allocation: http://c-faq.com/malloc/index.html. Really optional: check out the GNU implementation of malloc. What Happens When… You malloc but you don’t free? You write beyond your allocation? You free a pointer twice? You free memory that’s not your […]
CS 245 Lab 5 – Binary Search
First, if you have checkpoints left over from last lab, get them inspected during the first 15 minutes of this lab. Work in pairs, where possible. Prefer working with someone that you did not work with last week. The exchange of new ideas and perspectives is not an opportunity you want to rob yourself of. […]
