[prog] Definining an array in Visual C++

[Elizabeth Barham]

Here's a slight modification of your code, Kathryn, so as to handle
double []'s:

template <class _Tp>
class D_ArrayHelper{
  _Tp *tp;

public:
  D_ArrayHelper(_Tp * p): tp(p) {}
  _Tp & operator[](int x) { return tp[x] ; }
};

template <class _Tp>
class DArray {
   _Tp *tp;
  size_t n;
public:
    DArray(size_t n_size): n(n_size) {
        tp = new _Tp[n*n];
    }
     ~DArray() {  delete [] tp; }
    _Tp &operator () (size_t i, size_t j) {
          // assert(i < n && j < n);
          return tp[i*n+j];
    }

  D_ArrayHelper<_Tp> operator[](int x) { return D_ArrayHelper<_Tp>(tp + n * x); }

};
