combine UDP client and UDP server in C into one multithreaded P2P (peer-to-peer) application in C which is a client and a server at the same time. The program shall start two threads. One thread shall execute the send loop: display the prompt (see below); read user input; send it to the other chat application; repeat. The other thread shall execute the receive loop: receive a message from the other char application; display the received message; repeat. The send loop shall terminate when the user types '%stop' (less the quotes). The main thread shall wait for the other two threads to terminate.
