go slice memory-address

I have some experience in C and I am totally new to golang.

func learnArraySlice() {
  intarr := [5]int{12, 34, 55, 66, 43}
  slice := intarr[:]
  fmt.Printf("the len is %d and cap is %d \n", len(slice), cap(slice))
  fmt.Printf("address of slice 0x%x add of Arr 0x%x \n", &slice, &intarr)
}

Now in golang slice is a reference of array which contains the pointer to an array len of slice and cap of slice but this slice will also be allocated in memory and i want to print the address of that memory. But unable to do that.

http://golang.org/pkg/fmt/

fmt.Printf("address of slice %p add of Arr %p \n", &slice, &intarr)

%p will print the address.
