C++ array rev pointer

// using pointers
#include <iostream>

    // pointer1 pointing at the beginning of the array
    int *pointer1 = array,
  
        // pointer2 pointing at end of the array
        *pointer2 = array + array_size - 1;
    while (pointer1 < pointer2) {
        swap(pointer1, pointer2);
        pointer1++;
        pointer2--;

}
  
// Function to print the array
void print(int* array, int array_size)
