title: How to execute and compile a program in Xcode via command line in c and where's the executable?
body: <p>I'm trying to execute via command line a code written in C. I tried gcc -o file file.c, but it did not work. I need to learn how to compile and execute a code using gcc and llvm without graphical interface. Furthermore when I compile the program I cannot find the executable file in Finder (there's no Developer folder in Library).</p>
  
  <p>Thanks in advance. </p>
