Write and Run C in Xcode 13

In this video, I show how to create a new C programming language project or C programming language file in Xcode.

Where's the run button when you made a file instead of a project? Can't find it anywhere.

This is the way more simple and until now the unique way I got hahaha I tried run from terminal using gcc commands (this work) but when I will run ex: ./a.out or ./hello if I have set a name I get error and not run anything... thanks to shared this way.

And the run button just disappears at the end
