CODE EXAMPLE FOR CPP

reverse an array using pointers in c++

#include <iostream>

using namespace std;


int* reverse(int* list, int size)
{
  for (int i = 0, j = size - 1; i < size; i++, j--)
  {
    // Swap list[i] with list[j]
    int temp = list[j];
    list[j] = list[i];
    list[i] = temp;
  }

  return list;
}

void printArray(const int* list, int size)
{
  for (int i = 0; i < size; i++)
    cout << list[i] << " ";
}

int main(){
    int list[6] = { 1,2,3,4,5,6 };
    int *ptr = reverse(list, 6);
    printArray(list,6);
}
