Aserver s is designed for computers to test if they are located behind nats or not. the server has two public ip addresses, i1 and i2, and has allocated two ports, p1 and p2 (either udp or tcp port), for this purpose. note that the ip address and the port numbers are known to every computer which wants to use this service. (a) design your protocol so that a computer a, by exchanging packets with s, can test if it is located behind an nat or not. (b) assume it is behind an nat. repeat (a) if computer a needs to determine if the nat is a symmetric type or not.

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).
