Give a solution to the Producer-Consumer problem using the Wait(s) and Signal(s) instructions. The producers and Consumers will be sharing a common buffer BUF[0..N-1]. The Producers will be putting items in the array and the Consumers will be taking items from the array. We need to synchronize the two groups of processes so that the Producers will not be overwriting a full buffer and the Consumers will not be taking items from an empty buffer. Make sure that mutual exclusion is guaranteed when multiple Producers are trying to put items in the array and multiple Consumers are trying to take items from the array.

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).
