how to do this meta-programming? print the address of random element's address of a variable length of arrays?

[mw]

e.g.

int[] a = new int[la];
int[] b = new int[lb];
int[] c = new int[lc];
int[] d = new int[ld];


the func I want to write, e.g. for 2 arrays (instantiation) is 
like this:

void print_random_elem_addr(int[] x, int[] y) {
   auto i = random_int_between(0, x.length);
   auto j = random_int_between(0, y.length);
   print(&(x[i], &(y[j]));  // only single print() func call 
allowed!
}


But I want one generic function, which can be called as:

print_random_elem_addr(a, b);
print_random_elem_addr(a, b, c);
print_random_elem_addr(a, b, c, d);
...


My main question is how to meta-program (generate the parameter 
list) this line:
   print(&(x[i], &(y[j]));  // only single print() func call 
allowed!


Thanks!
