Reverse Array using Pointers in C++

#include <iostream>
using namespace std;
void reverseArray(int* arr, int size) {
    // Pointer to first element
    int* start = arr;
    
    // pointer to last element
    int* end = arr + size - 1;
    // Until both pointers meet
    while (start < end) {
        // Swap values at start and end
        int temp = *start;
        *start = *end;
        *end = temp;
        // Move pointers
        start++;
        end--;
    }
}
int main() {
    int arr[] = {10, 20, 30, 40, 50};
    int size = sizeof(arr) / sizeof(arr[0]);
    reverseArray(arr, size);
    for (int i = 0; i < size; i++)
        cout << *(arr + i) << " ";
    cout << endl;
    return 0;
