I've installed the XCode compiler on my MacBook Pro, and for some reason, I think it doesn't it has all of the required libraries. Here is a screenshot of all the errors it gave me when I entered a code (which worked on the compilers at school): http://s899.photobucket.com/user/ajedrez1/media/4f37f167-fca1-4024-884d-3d79e5e7a37b_zpsdfa14d8a.png.html?state=copy
I'm not getting how it's not recognizing the usernames, passwords, or even simple things like endl (end line). A friend of mine who installed it says it's working fine for him (and he actually installed it into my computer remotely, so I'm assuming he installed everything he put onto his own computer).
Thanks for your help, everybody.
