Reverse an array

Write both iterative and recursive methods for reversing an array

Iterative Method:

void reverseArray(int arr[], int start, int end)

{

  int i;

  int temp;

  while(start < end)

  {

    temp = arr[start];

    arr[start] = arr[end];

    arr[end] = temp;

    start++;

    end--;

  }

}  

Recursive Method

void reverseArray(int arr[], int start, int end)

{

   int temp;

   if(start >= end)

     return;

   temp = arr[start];

   arr[start] = arr[end];

   arr[end] = temp;

   reverseArray(arr, start+1, end-1);

}
