Write a program to calculate the sum of the numbers from 1 till upper bound. If upper bound is 5, sum should be 1 + 2 + 3 + 4 + 5 = 15. If upper bound is 11, sum should be 1 + 2 + ... + 11 = 66. If upper bound is 100, sum should be 1 + 2 + ... + 100 = 5050.

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).
