Suppose a tcp entity receives a 1.5 megabyte file from the application layer andthat the ip layer is willing to carry packets of maximum size 1,500 bytes. calculate the amountof overhead incurred from segmenting the file into packet-sized units. ignore tcp overheadheader. ignore that ip fragments data at 8-byte boundaries. assume that all packets are ofsame size (except the last one) and each packet has an overhead header of 20 bytes.

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).
