Reverse an array code in c++

 Reverse an array arr[] = {a, b, c, .......};

#include <iostream>

int reverse(int arr[], int size)

{

    int low = 0, high = size - 1;

    while (low < high)

    {

        int temp = arr[low];

        arr[low] = arr[high];

        arr[high] = temp;

        low++;

        high--;

    }

    for (int i = 0; i < size; i++)

    {

        std::cout << arr[i] << " ";

    }

}

int main()

{

    int arr[] = {1, 2, 3};

    int size = 3;

    reverse(arr, size);

    std::cin.get();
