c Define a class named Document that contains a member variable of type string named text that stores any textual content for the document. Create a function getText() that returns the text field and a way to set this value. Next, define a class for Email that is derived from Document and that includes member variables for the sender and recipient. Implement appropriate accessor and mutator functions. The body of the email message should be stored in the inherited variable text. Test both classes in main. Make sure you have appropriate constructors.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e. g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
