Client/Server messaging application written in C by Mario Bonsembiante, as final project for the exam "Computer networks". This is a terminal-based (no GUI) app to exchange text messages between clients, exploiting TCP/UDP sockets. The server is used to store pending messages when the clients are offline and knowing the ip of other clients. Specification (in italian) are available here: http://www2.ing.unipi.it/c.vallati/files/reti/Progetto2017.pdf or in the file projectSpecification_ita.pdf.
