How do productivity programs most benefit the way we work and live?

They enable us to save trees because we have become much less reliant on the use of paper at home and at work.

They provide us with ways to communicate, display, and work with information more quickly and accurately.

They push us into a new digital age in which all aspects of our lives will continue to become easier and less complicated.

They make us less tolerant of waiting and working for communication responses, research results, and mathematical

calculations.

Help please taking the unit test

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
