Creating the client
The client can be created using the RPC package's rpc.DialHTTP function, using the same host-port to obtain a client:
if len(os.Args) != 2 { log.Fatalln("Please specify an address.")}client, err := rpc.DialHTTP("tcp", os.Args[1])if err != nil { log.Fatalln(err)}defer client.Close()

const hp = "H.P. Lovecraft"var books = []common.Book{ {ISBN: "1540335534", Author: hp, Title: "The Call of Cthulhu", Pages: 36}, {ISBN: "1980722803", Author: hp, Title: "The Dunwich Horror ", Pages: 53}, {ISBN: "197620299X", Author: hp, Title: "The Shadow Over Innsmouth", Pages: 40}, {ISBN: "1540335534", Author: hp, Title: "The Case of Charles Dexter Ward", Pages: 176}, ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
