This program is a simple client-server messenger implemented in C. It uses UDP sockets to establish a relay between each communicating node, allowing multiple users to send messages to server simultaneously.
To compile this program, you need the latest version of GCC compiler and all standard UNIX network libraries. You can not run this program on winsock.h library for Windows.
After compiling simply follow instructions in the menu. You can either receive messages (server side) or send messages to server (client side).
