Outline the design of an authenitication scheme that "learns". the scheme would initially have some information about a user - e. g. the username and password. as the use of the computing system continued, the authentication system would "gather" additional information, e. g. programming languages used, dates and times of use, etc. the authentication requirements would become more personalized with time. list the the types of information the system could gather. assume that the authentication scheme is for a laptop or a phone. consider how the authentication information would be presented and validated. does the user answer true/false or multiple choice questions. does th need to interpret natural language prose?

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).
