Write a C++ program to check a given array of integers, length 3 and create a new array. If there is a 5 in the given array immediately followed by a 7 then set 7 to 1

#include <iostream>
using namespace std;

int *test(int nums[], int arr_length) {
   
         for (int i = 0; i < arr_length - 1; i++)
            {
                if (nums[i] == 5 && nums[i + 1] == 7)
                    nums[i + 1] = 1;
            }
            return nums;
}

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