Program Description Implement a file transfer service using TCP socket as shown in the following figure: In this service, it is the client that initiates the TCP connection with the server. After the connection was established, the client sends the name of the file it wants to receive to the server. The server will try to open the requested file. If the file opening is successful, the server will send the file to the client; if it is not successful, the server will send back an error message. The server will close the TCP connection once the file is completely sent. The closing of the TCP connection is used to indicate the end of the file transfer
