Answer to Question #214411 in C++ for Hemambar

Question

Create a class called Transmitter. It has three unsigned int private data members: pay_load,

parity and data_packet; It has one function called parity_bit(). It calculates parity bit by XORing

all pay_load bits and assign the value to parity. By using function get pay_load(), pay_load is got.

data_packet is calculated by multiplying parity_bit with 32768 and add the product with (pay_load

– 32768). Create another class called Receiver. It has unsigned int private data members Rx_Pkt

, Rx_Data and E_Flag. Rx_Data is got from Rx_Data as given below. First E_Flag is calculated

from Rx_Pkt by XORing all bits. If E_Flag is zero, then Rx_Data = Rx_Pkt – 32768, Else a

message should warn about corrupted packet. Derive a class called Tranceiver from the above two

classes and check the functionalities. Use any other functions if needed.
