Socket-Programming

Use socket programming to implement a simple client and server that communicate over the network and implement a simple application involving Cash Registers. The client implements a simple cash register that opens a session with the server and then supplies a sequence of codes (refer request-response messages format) for some products. The server returns the price of each one, and also keeps a running total of purchases for each clients transactions. When the client closes the session, the server returns the total co st. This is how the point-of-sale terminals should work.
