Consider the bag from Chapter 4 (using a dynamic array). The pointer to the dynamic array is called data, and the size of the dynamic array is stored in a private member variable called capacity. Write the following new member function: (C++ LANGUAGE)

void bag::triple_capacity( )

// Postcondition: The capacity of the bag's dynamic array has been

// tripled. The bag still contains the same items that it previously

// had.

Do not use the reserve function, do not use realloc, and do not cause a heap leak. Do make sure that both data and capacity have new values that correctly indicate the new larger array.
