How to use gcc instead of clang on macOS, specially M1? (Help)

  apple-m1, c++, clang, compilation, gcc

I code in C++,

I was a Windows user, recently switched to mac.
I downloaded gcc-10 from homebrew but still, whenever I compile on any editor, it got compiled with Clang.
Then I deleted Clang by going to the directory where it was stored, I thought it will then compile with GCC.
But now it stops compiling and throwing error messages.

Q.Why do I wish to use gcc instead of clang?
-> Clang doesn’t have <bits/stdc++.h> header and while solving one question I got to know it doesn’t have unordered map also (read on StackOverflow later).

-> And I don’t know what more is not there in clang.

Can anyone please tell me
either how to successfully compile C++ using gcc on MAC or can tell me all the difference between clang and gcc and how should I manage.

Even I talked with apple care for about 45 mins and they also don’t know the solution.
