First of all, welcome to Code::Blocks forums.
To make a few things clear here Necer149, this forum is for support to Code::Blocks IDE and not how to teach you programming.
It's very encouraging to know a kid like you at the age of 13 finds programming interesting, let alone overwhelming, therefore I would like to ask you the following questions:
- What language do you know?
- How well do you know it?
- What is your currect objective with programming other than the aforementioned SDKs you have mentioned?
- Have you seen other programming languages, like Python or Lua?
My suggestion would be, pick up the language you like the most, read a couple of books, then start messing with other people's code, don't afraid to make mistakes; through mistakes you master your tools, because let's face it; a programming language it's a tool for us humans to express our ideas and concepts.
You may Google a few book titles or for some stackoverflow links that suggest books by experts, and basically that's it.
Practice, practice, practice.
