Hello everyone, as you may notice by the question I am quite new to the whole world of programming. I've been using Xcode to create executable files to rewrite and run some of the exercises that my teacher gives us. The question is the following: is it possible to create a single executable file? Because now i can only create a file inside a project and when I try to write an exercise with the tag "int main(void)..." it gives me an error and a friend said that it is because it is already used in the "main " file inside the project. So can I have a single file to run and create lots of them with the tag "int main (void)" and run them?

the question was about creating executable files in c individually. I wanted to know if it was possible to create only executable files in C without having to create projects every time.

It is not clear what you mean by the tag "int main (void)", so I may be mistaking something, but with my best guess...

If you want to build many executables in a single project, you may need to add a Target for each executable you want to build.

In my opinion, it is easier to create as many projects as needed to build many executables. If some parts of them use exactly the same files, you can easily copy them from a project to another project.

If you are writing lots of small programs for a C programming course, you are better off using a text editor like VSCode, Sublime Text, BBEdit, or TextMate to write your code instead of Xcode. Xcode requires a project to create an executable file. You can't just create a C file in Xcode and run it.

I know TextMate has a C bundle that lets you run your programs from inside TextMate by choosing Bundle > C > Run. I'm sure the other text editors I mentioned have ways to run your programs from the editor.

Yes, if you are trying to create individual C files, it's pretty easy to do that without an Xcode project. You can write your code in your favorite text editor, and then use the gcc command to compile your code from the Terminal app.
