Write a simple TCP program for a client that reads a line of text from its standard input (keyboard) and sends the line out its socket to the server. The server reads the line from the socket and prints it in its standard output (screen). The server then reads a line from its standard input (keyboard) and sends it out its socket to the client. When the client sends ! the server should reply back bye to the client and it closes the socket.

Sample Output Client:

Client: Hi there

Server: Hello

Client: How are you?

Server: I am fine

Client: ! Server: Bye
