 Cody also changed the location that it used `gets()` to be `fgets()` instead to
 make it safer and to prevent annoying warnings during compiling, linking or

 One might think that simply changing the `gets()` to `fgets()` (with `stdin`)
 would work but it did not because `fgets()` stores the newline and `gets()` does

 With `fgets()` the code `if(A(Y)) puts(Y);` ended up printing an extra line
