C++ array rev pointer

// CPP program to reverse array
// using pointers
#include <iostream>

// Function to swap two memory contents
void swap(int* a, int* b)
{
    int temp = *a;
    *a = *b;
    *b = temp;
}
  
// Function to reverse the array through pointers
void reverse(int array[], int array_size)
{
  
    // 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)
{
  
    // Length pointing at end of the array
    int *length = array + array_size,
  
        // Position pointing to the beginning of the array

// Driver function
int main()

    // Array to hold the values
    int array[] = { 2, 4, -6, 5, 8, -1 };
  
    cout << "Original ";
