Where should I start if I want to get into coding?

Where can I even begin? I'm good with computers in general and I've coded some websites in HTML but that's about it. I'd like to get into C++ but I have no idea where to start. Where did you guys go to first when you wanted to learn C++? Any hints or ideas? I understand it's hard but I'm willing to learn and I'm almost fifteen. Also, is it hard to make an injector?

just go buy C++ book its show u step by step about coding.
