You can just say `make hello` — no Makefile required! And then run with `./hello` instead of invoking the more obscure a.out

Obviously that doesn’t scale, but for a beginner it’s simple.

TIL

  $ ls
  $ cat >a.c <<EOF
  int main(){return 42;}
  EOF
  $ make a
  cc     a.c   -o a
  $ ./a; echo $?
  42
  $

I don't know about `ls`, but I typically type something so short on one line:

    $ echo 'int main(){return 42;}' > a.c; make a && ./a; echo $?
