Which elements in the array are the arguments int left and int right referring to?
The first and last indexes?

template <class type>
void mergesort(type a[], int left, int right)
{
  if(left<right)
    {
      int mid=(left + right)/2;
      mergesort(a, left, mid);
      mergesort(a, mid+1, right);
      merge(a,left,right);
    }
}

So basically if sorting an array of 10 elements you would pass
mergsort(Array, Array[0], Array[9])

correct?

no, (Array, 0, 9); -> the *indexes* not the *values contained in the indexes*
