- A blacksmith is shoeing a miser's horse. The blacksmith charges ten dollars for his work. The miser refuses to pay. "Very well", says the blacksmith, "there are eight nails in each horseshoe. The horse has four shoes. There are 32 nails in all.

How much does the miser have to pay?​

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).
