Design a class with floating-point pointer members. The constructor has an integer parameter count.
It allocates count element space for pointer members to store data. The destructor releases the space pointed by the pointer.
In addition, two function members are designed to accomplish the following functions:
(1) stores data in the space pointed by the pointer;
(2) Returns the average of these numbers.
