Answer 1

Programming languages are like tools in a tool kit. You wouldn't use a wrench to hammer a nail into a wall. It wouldn't be efficient, although you probably could somehow. Just like that, most programming languages can be used for the same thing, but have different amounts of efficiency and their own specifications. C++ is used for programming 3D open world games and such. It is a very fast, although difficult language. if you want to program a simple 2D game, then use Java. C++ is also what most softwares are made of.

To quote a post on Upwork.com, "C++ is considered a more prestigious language used for applications such as games, operating systems, and very low-level programming that requires better control of hardware on the PC or server. If your application is a simple Web or desktop application, most developers will urge you to work with C#..."

Essentially, yes, C# is easer, but also most use it for simple things. If you want to have more control and make big games/operating systems, use C++. It's fast.
