C++

please use get and set methods

Design and implement a Student class that derives from a Person class. A student has a COS id, total unit balance, and an account balance in dollars. The Student class will include account deposit and withdraw methods as well as an add unit method which appropriately decreases the account balance by $46 per unit. Instantiate two Student objects dynamically (No Ul and no Arrays please.) For both objects, add 12 units and then display an account statement. Before exiting the program, properly de-allocate the memory for both objects
