Thread: String output

Code:

int main()
{ string s = "12a34b56c78d";
   int size = 12;
   writeStuff(s,size);
   return 0;
} // end main
void writeStuff(string s, int size)
{     if (size > 0)
     {     cout << s.substr(size-1, 1);
            writeStuff(s, size-3);  
      }  // end if
}  // end writeStuff

What is supposed to be the output of this?
