c++ - Reverse Contents in Array

Question

I have an array of numbers that I am trying to reverse. I believe the function in my code is correct, but I cannot get the proper output.

The output reads: 10 9 8 7 6. Why can't I get the other half of the numbers? When I remove the "/2" from count, the output reads: 10 9 8 7 6 6 7 8 9 10

void reverse(int [], int);

int main ()
{
   const int SIZE = 10;
   int arr [SIZE] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

   reverse(arr, SIZE);
   return 0;
}
void reverse(int arr[], int count)
{
   int temp;
   for (int i = 0; i < count/2; ++i)
   {
      arr[i] = temp;
      temp = arr[count-i-1];
      arr[count-i-1] = arr[i];
      arr[i] = temp;

      cout << temp << " ";
   }
}

Answer 1

This would be my approach:

#include <algorithm>
#include <iterator>

int main()
{
  const int SIZE = 10;
  int arr [SIZE] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
  std::reverse(std::begin(arr), std::end(arr));
  ...
}
