 Here I used some special macros, the `$(CC)` macro is used to let users specify their preferred C compiler in the `CC` environment variable, if it is not set it will default to `cc` or `c99`. This is preferable to hard coding `gcc`, `clang`, or whatever compiler you might use since not everyone will use the same tools as you. The `$(CFLAGS)` macro is added to let the user specify flags to send to the C compiler in their `CFLAGS` environment variable. Lastly, and maybe most importantly, the `$@` macro evaluates to the name of the current target, which in this case is `$(full_name)`, which in turn evaluates to `hello_world`. Ultimately this target will run the following shell:
 
-```
+```sh
 cc -o hello_world hello.o world.o

 Now make knows how to make our full `hello_world` program, but why do we specify that `hello.o` depends on `hello.c`? We write the source ourselves, so surely there is no need to tell make this? Well, the beauty of make is that it checks the last edited date of depends to rebuild targets. In other words, if we edit hello.c and rerun make it will only run the following:
 
-```
+```sh
 cc -c -o hello.o hello.c
