another question:

can I combine these two line:
++*ptr;
++ptr;
into a single statement?

How do you increment a pointer to an integer
(increment both the pointer and the content of the pointer)?

How about:

#include <iostream>
using namespace std;

int main()
{
   int array[] = {0,1,2,3,4,5,6,7,9};
   size_t arraySize = sizeof(array)/sizeof(array[0]);
   int *ptr = array;

   // display initial array
   for(size_t i=0; i<arraySize; ++i)
       cout << array[i] << '\n';

   cout << "\n\n";

   // do the incrementing
   while (ptr != array+arraySize )
   {
       ++*ptr;
       ++ptr;
   }

   // display modified array
   for(size_t i=0; i<arraySize; ++i)
       cout << array[i] << '\n';

   return 0;
}
