I would use the reverse() function from the <algorithm> library.
Run it online: repl.it/@abranhe/Reverse-Array
#include <iostream>
#include <algorithm>
using namespace std;
int main()
{
int arr [10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
reverse(begin(arr), end(arr));
for(auto item:arr)
{
cout << item << " ";
}
}
Output:
10 9 8 7 6 5 4 3 2 1
Hope you like this approach.
