Write a class, ConsumersCls. The class contains two attributes $($consumerID and a purchase amount$).$ The class must have a twoparameter constructor and member functions such as get and set member functions and a member function calculate$().$ The calculate$()$ function is used to calculate a discount amount in dollars based on the conditions below. Implement the class and the main$()$ function. Logic for the Calculate$()$ function to calculate the discount amount: If the purchase amount is between $$1\mathrm{.}0-$$$2000\mathrm{.}0,$ the discount rate is $2\mathrm{.}5\%.$

If the sales amount is between $$2001\mathrm{.}0-$$$6,000\mathrm{.}0,$ the discount rate is $3\mathrm{.}5\%.$

If the sales amount is between $$6001\mathrm{.}0-$$$10000\mathrm{.}0,$ the discount rate is $4\mathrm{.}5\%.$

If the sales amount is greater than $$10000\mathrm{.}0,$ the discount rate is $5\mathrm{.}5\%.$
