Part #3: More Messages

Now we will allow the client to send as many messages as it wants. Instead of ending the program after

receiving the modified message from the server, we will allow the client to keep sending messages until

it sends the word "end" to the server. Once the word "end" is sent to the server the program will end

after receiving the server's response to that "end" message. Hint: For this part all you must modify is

the client file.
