Explanation:

Server Code:

  1. Setup:
    • Creates a socket using socket().
    • Configures server address serverAddr with AF_INET (IPv4), INADDR_ANY
      Advertisement
      (binds to all available interfaces), and PORT.
    • Binds the socket to the address using bind().
    • Listens for incoming connections with listen().
  2. Handling Clients:
    • Uses accept() to accept incoming client connections.
    • Spawns a new thread to handle each client connection. The handleClient()
      Advertisement
      function:
      • Receives messages from the client.
      • Prints the received message.
      • Sends the same message back to the client (echo server).
    • Closes the client socket when done.
  3. Error Handling:
    • Checks for errors at each step and prints appropriate error messages using perror().

Client Code:

  1. Setup:
    • Creates a socket with socket().
    • Configures server address serv_addr with AF_INET and PORT.
    • Converts IP address to binary form with inet_pton() and connects to the server using connect().
  2. Interaction:
    • Sends user input to the server with send().
    • Receives and prints the server’s response with recv().
    • Exits the loop if the user types “exit”.
  3. Error Handling:
    • Checks for connection errors and displays messages if needed.
