C++ Array Pointer Accessing each array element with the increment operator on its pointer

#include <iostream>
using namespace std;
int main()//from ww  w .ja v a2  s. c  o  m
{
   const int NUMS = 5;
   int nums[NUMS] = {16, 54, 7, 43, -5};
   int i, total = 0, *nPt;
   nPt = nums;    // store address of nums[0] in nPt
   for (i = 0; i < NUMS; i++)
      total = total + *nPt++;
   cout << "The total of the array elements is " << total << endl;
   return 0;
}
