How to interlace two integers in C?

Let say I have two ints

a = 1234 b = 45678

Now I want to "interlace" them into a third int c that looks something like this c = 415263748 assume the the length of these don't change. So far I've been able to do this:

unsigned interlace(unsigned x, unsigned y) {      unsigned pow = 10;      while(y >= pow)          pow *= 10;      return x * pow + y;          }
