Which complier should i use for c++

Answer 1

GCC is good and will be the default if you're on Linux.
But that's a compiler which you shouldn't worry about a lot,

You probably are asking about IDEs/Editors, some of the good ones will be Code::Blocks, Visual Studio Code(with the code runner extension), Visual Studio.
Don't use Turbo C++. It's old and most of what you learn here won't work in it.

Code::Blocks is easy to use and great for beginners while Visual Studio, being the jack of all trades & arguably the best, can be quite overwhelming for beginners. So yeah, you can start using Code Blocks :)
