What sources are better to choose for studying the principles of programming, so to speak, the base?

Question

IT education

I became interested in programming 2 months ago, I tried to write something, and you know, it fascinated me, now I want to understand where to start learning, I started writing in C ++, I read that it was supposedly very difficult, but I don’t know how I sat down to read, watch, try, I'm ok! Now I want to decide in which direction to move: 1) Software on a PC, 2) Android, 3) Ios, 4) Web, etc!
Of course, it’s up to me to choose, but still, all this is united by a certain base, the foundation of knowledge, so I ask them!)
Google gave a lot of options that my eyes run wide! =)
