Here's how you answer any one-line LPC code question:

Start DGD with the kernel library.
Login as admin.
Type:

    code p = "/some/path/file.c"; sscanf(p, "%s/%*s", p); return p;

If the argument to 'code' does not end in a semicolon, it's assumed
to be an expression and you don't have to return anything.

    code sscanf("/some/path/file.c", "%*s/%*s")

Variables a, b, ... z are predeclared with type mixed.  Any code
with a semicolon in it is a statement or series of statements, and
should end in the return of a value, followed by a last semicolon.
You can declare further variables of your own, if you like.

sscanf() is useful, but also take a look at explode().
