First set of notes. (Tue Sep 2,2014)
Went over a new project for, just for kicks.
Started to play with the class chat.
Went over this:
screen -ls if “no socket” –>screen
irssi /server irc /join csci / lab46
- ———
* POINTERS *
- ———
int a; (pointers are used to show were everything is located)
Spent a little time learning the differences between 32 bit and 64 bit systems.
int a; (gives you a part of memory) int b; (also give you the amount you want but it might not be the one right aft$
int *c; (*- dereferencing operator)
Pointers are the same size but we can choose how much memory we want. int a=5; int *c; c=&a;
Pointers are no more than just stomething that contains an address to something$
int *g=(int*)malloc(siveof(int)*4) Went over a new project for, just for kicks.

Learned about structs and how they work. Structs have layers and so do onions.
