The following programs must be written in C using the POSIX socket libraries. Code must be able to compile and run on UNIX. There are many examples of client/server code on the internet and you are welcome to take code and modify to fit this assignment so long as the code source is referenced in the code comments. The task is to write a client that will connect to a server via UDP or TCP messages. Once the client connects the server will respond by sending some text (a few words is enough) to the client and then close the connection. The code should print out messages to show what is happening. "Connecting to...", "Sending image...." etc. You can write code for two different servers for the two different message types (UDP and TCP).

1. Write a UDP client/server with filenames clientUDP.c and serverUDP.c

2. Write a TCP client/server with file filename clientTCP.c and serverTCP.c
