Write a C++ program to compute the sum of the two given arrays of integers, length 3 and find the array which has the largest sum

#include <iostream>
using namespace std;

static int *test(int nums1[], int nums2[])
          {
              return nums1[0] + nums1[1] + nums1[2] >= nums2[0] + nums2[1] + nums2[2] ? nums1 : nums2;
          } 

int main () {
   int *p;
   int nums1[] = { 1, 5, 7 };	
   int nums2[] = { 1, 5, 3 };
   int arr_length = sizeof(nums1) / sizeof(nums1[0]);
   p =  test(nums1, nums2);
   cout << "\nNew array: " << endl;
   for ( int i = 0; i < arr_length; i++ ) {
      cout << *(p + i) << " ";
   } 
   return 0;
}
