Codecademy.com is a free place to start if you're looking to do websites.
Maybe someone else here can suggest a good place to get started with C?
Codecademy is good.
Udemy is another place to look at; they have user submitted tutorials, some are paid, others are free. PluralSight is another, but that is paid, after a 10-day free trial. Surprisingly I still find some books to be relevant; at least as a starting point and reference guide.
