So in that case what you tell me to do?
What do you mean by "case," exactly? The first step is just picking a programming language, as was said in that video. People have lots of opinions, and I certainly have my own. But really, just pick a dang language and roll with it. It sounds like you've picked C++. Okay, cool, roll with it. Just start googling things about it ("C++ tutorial" is a decent thing to google for). But again, like was said on that video, it would be a good idea to invest in a book (so google "C++ book" or something and pick a book). Stay away from books that promise you'll learn C++ in 10 days or whatever (
someone wrote an article about this once, and the reason I say this is because they're lying to you if they say you'll learn language X in a matter of days/weeks; learning to program is a large time investment, and a book that lies on its cover isn't doing you any favors).
Someone might come up and say "No! you should learn language X first instead!" Sure, it's totally possibly language X might be easier to start with, but if you've already started, just keep going with your chosen language; you don't want to lose any momentum you may have built up. Learning one language doesn't prevent you from learning another later. It's not the end of the world if you pick a difficult language, and learning to program will still be challenging if you pick an easy language. Just recognize it'll take time and work with whatever you chose, but if you just bounce back and forth in circles between picking language X and language Y and language Z, you'll never get anywhere. Pick one, roll with it, read everything you can about it, and practice
a lot, writing all sorts of small programs. Be curious! Explore! Try things!
In every search that i do everybody says that's is not important to know C in order to learn C++.
And the reason they keep saying that is because it's not. They're two different languages. You'll be just fine if you just focus on the one you've picked.
