Write a class, ConsumersCls. The class contains two attributes (consumerID and a purchase-amount. The class must have a two-parameter constructor and member functions such as get and set member functions and a member function calculate(). The calculate( ) is used to calculate a discount amount in dollars based on the conditions below. Implement the class and the main( ). Grading Criteria: (10 points) The class implementation is coded correctly. (10 points) The calculations in the member function calculate ( ) are performed correctly. If the purchase-amount is between $1.0-$2000.0, the discount rate is 2.5%. If the sales-amount is between $2001.0-$6,000.0, the discount rate is 3.5%. If the sales-amount is between $6001.0-$10000.0, the discount rate is 4.5%. If the sales-amount is greater than $10000.0, the discount rate is 5.5%. The main ( ) program/function must do the following tasks: Create an array of three objects (8 points) or one object (5 points), ConsList, of the class calling/invoking the constructor. As a result, the data members/private members of the class will contain the assigned values passed to the constructor parameters. (5 points) Create one object, Cons4, of the class. Use the object to call the set member functions. As a result, the data members/private members of the class will contain the assigned values passed to the set member functions. (4 points) Use a loop to iterate through each object in the ConsList in which it calls the member function calculate(). (2 points) Use Cons4 to call the member function calculate( ). (4 points) Display the names, sales amount, and discount amount(s) of all objects, ConsList, and Cons4. Copy the code (the class implementation and main ( ) function into the answer box.
