ottery program. The program randomly generates a two-digit number, prompts the user to enter a single two-digit number, and determines whether the user wins according to the following rules. Write a loop to let the user play as many times as the user wanted. Use a sentinel or flag to quit out of the loop. You must pick the correct loop for this question. Each time the user continues to play, the program will generate a new two-digit random number until the user enters -999 to quit.

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).
