On second thought, I think no extra parameter is required. I think this 
qualifies as the C++ equivalent:


#include <vector>

typedef std::vector<int>::iterator iter;

void UpdateString(const iter iFirst, const iter iSecond, int K)
{
     const int SIZE= iSecond-iFirst;

     if(SIZE== 0)
       return;

     else if(SIZE==1)
     {
         *iSecond+=K;
         return;
     }

     else
     {
         UpdateString(iFirst, iFirst+ SIZE/2 -1, 19);
         UpdateString(iFirst+ SIZE/2, iSecond, 27);
         return;
     }
}


int main()
{
     using std::vector;

     vector<int> vec(10);

     // Pass a subrange
     UpdateString(vec.begin(), vec.begin()+4, 0);
}
