What happens if you execute the client program before the server one? 2. Add a loop to the programs to make it repeat the task many times. 3. Modify the programs to create a chat between the server and the client: The client sends a text to the server. The server prints the received text and sends an answer to the client. Use a loop to repeat the task.
