i cann`t understand this code

Code:

---

char code[] = "bytecode will go here!";
int main(int argc, char **argv)
{
  int (*func)();
  func = (int (*)()) code;
  (int)(*func)();
}

but i cann`t understand this :

Code:

---

  int (*func)();
  func = (int (*)()) code;
  (int)(*func)();

---

can someone explain to me please what this mean !!!!

> int (*func)();
func is a pointer to a function. It takes unspecified parameters, and returns an int.

> func = (int (*)()) code;
Make func point at the code. The red bit is the cast to make it happen silently.

> (int)(*func)();
Call it, though the (int) is of dubious use.
