The following program sets up a single client/server connection. When the client connects, the server reads any incoming data as text and prints it out one line at a time. If the server receives the string “shutdown”, then it closes the socket and exits. Download this program Download this program into GCC and run the code. Then update your code to allow for the server to manage concurrent connections on the same port. Use IP address 127.0.0.1.
