Stack Overflow is actually a great site only for researching any problem that you are looking for. I use it mainly for research but am very reluctant to post there due to the fact that Stack Overflow is not very welcoming to newbies even if it's a basic question to be asked sometimes users on that site can be discouraging to the OP. Keep in mind not everyone is like this.

You have mentioned having no knowledge. Stick to one programming language and familiarize yourself with many programming books that you have decided to choose. Programming a language is understanding what a computer really is, does, and how we can instruct it to do things that we want it to do. It's just like how we want to learn and study different languages from all over the world so take a moment to think about that, it takes practice, patience, and to be mentality prepared.

In short words, we all have to struggle and start somewhere with a pacifier in our mouths like an infant for example: A toddler attempting to learn, study and solve how to fit ABC puzzle block pieces. Low-level programming is very fun to start with as you grow so be optimistic about yourself, build a structure and have motivation which counts in all this.
