Assignment Operator 4

• Third Attempt - a charm

IntArray& IntArray::operator =(const IntArray& b)
{
  if (this != &b)
    {
      delete [] data_;
      size_ = b.size_;
      data_ = new int [size_];
      // check for failed allocation
      for (size_t i = 0; i < size_; ++i)
        data_[i] = b.data_[i];
    }
  return *this;
}
