"What is C++?"

Well, C++ is a programming language.
 It's primarily for applications that are very demanding on performance, energy consumption, speed. If you don't have serious constraints on your problem, then you can probably do with some other language. But if you are really concerned about reliability, performance, response time, C++ becomes a good choice.

Why learn C++?

I mean the first is it's really useful. That is, there's so many things that are programmed in C++ and the space program in C++. 

Your cameras are probably programmed in C++. Your cell phones have C++ on it. The new data science stuff has C++. Your self-driving cars are C++.There is C++ on miles and miles over it. It's all over the place. 

So, it doesn't really matter much what you're interested in. There would be a job for writing C++ in that field. Secondly, it's a language with a lot of features. 

So, you can use it to learn the fundamentals of quite a few variations of programming. And so, you can learn how to work with data structures, you can learn how to write algorithms, you can write very high level generic code in it and you can fiddle with the bits and the hardware in it. A lot of languages are built to do one thing or they protect you against some of the unpleasantness of the real world, to the point where you can't actually learn how to deal with it. 

And so, C++ can be very useful as a learning tool to learn how to program. And then of course, what you learnt you can use.

3- Where C++ is used ?

As a person, I like to see C++ being used in interesting places like your camera there, the Mars rovers, telescopes. I work in the finance industry just now. A lot of the networking is done in C++. In the games industry, most of the graphics and the animation kind of stuff is in C++. 

So, as most of the animation in Hollywood, by the way, I'd forgotten about that. We mentioned cars, there's a lot of C++ in cars. BMW use C++ sharp, and I've one of their cars, it's C++ that controls it. I used the controls. And in these days, the self-driving cars, a lot of that work is in C++, too. 

We're talking about energy. The oil industry uses it, and the wind turbines are using it a lot. I was over in Denmark many years ago teaching C++ to some of the people that builds the biggest wind turbines in the world. So, one of the things that I find really cool about C++ is whatever you are interested in, it's a very good way of getting in and talking to people doing these interesting things and in interesting places.

 I guess a lot of the things are just more mundane but the interesting things, the unusual things is what you can talk about. Your smart watches, the smartphones, and things like that.

4- C++ different from other programming languages?

C++ differs from most more modern programming languages by working directly on the hardware and working very efficiently with the hardware and then having done that it provides really strong abstraction mechanisms that are very powerful very modern so that you don't have to deal with the low-level stuff all the time and you can still be efficient.
