$1$ Project $3$a: The Client and Single$-$threaded Server Overview For Part A$,$ you will implement both a server and client which will communicate over the network by exchanging messages and checking that the messages are in the correct format. $1\mathrm{.}1$ Requirements $1\mathrm{.}1\mathrm{.}1$ Source files and arguments $$ You MUST implement two source files in this part: the client $($tcpclient$.$c$)$ and the server $($tcpserver$.$c$).$ You MUST provide a makefile that will create the executables tcpclient and tcpserver. You SHOULD include all and clean rules in your makefile. $$ The client MUST take three arguments as input: server IP address, server port number, and an initial sequence number, in that order. $$ The server MUST take a single argument as input: the server port number. The server MUST be listening on this port for the entirety of execution. $$ The client and server SHOULD gracefully exit if a user provides an incorrect number of arguments. You MAY print a helpful message regarding the expected syntax.
