Broadcasting Server to Client C - c

Question

I am trying to broadcast a UDP message from the server to client. I would like for the server to send the broadcast to the client and then for the client to acknowledge the broadcast. They both compile with no errors but the server will not send the broadcast. The server says it successfully binds. Any tips would be helpful please.
