Im new to programming but im trying my best ?

The problem is that the technologies you've picked don't really work well together - HTML, CSS, and Javascript are all Client side web browser based stuff, and C++ isn't used for web stuff at all in the way you mean (though it may be used to develop library code that is called on the server side by other software).

Plus, I think there is a good chance you are going about this all wrong.
Forget video tutorials - particularly on YouTube - as they aren't generally made by people who know how to make a video, how to teach, or (in most cases) even how to code.

The first thing you need to learn is how to code, how to think like a developer - and that isn't a quick process, it takes practice to build up the skill set, in the same way it does to learn to ride a bicycle. You can watch the Tour de France as much as you like, but that won;t help you stay upright in the real world!

So what I'd suggest is that you pick a relatively simple - but powerful - language and get a good book on it (Addison Wesley, Wrox and Microsoft Press all do good ones) then work your way through it from cover to cover doing every exercise yourself. A course would be better (a real human can rephrase things you don't understand) but even then you need to practice, p[ractice, practice to get anywhere.

I'd suggest looking at C# - it's powerful, easy to learn, and comes with a massive amount of framework behind it. And it can be used for desktop, console, web, and even mobile development! It's also free to beginners: Microsoft will give you a copy of the Community Edition if you just google for it and download it from their site.

Give it a try, and good luck!
