Once a connection has been achieved between the client program and the associated server

thread and both programs have set up their respective socket streams for I$/$O$,$ the game begins

with the server thread generating a random sequence$/$code of $4$ colored pegs. Each peg is one

of six $$colors$$ R $($red$),$ Y $($yellow$),$ G $($green$),$ B $($blue$),$ W $($white$)$ or O $($orange$).$ Repeated colors

are allowed within the code$/$sequence$.$ So for example, our game sequence might be RGGW$.$

Each turn in the game consists of the player attempting to guess the $4-$color sequence. The

client program will prompt the user to enter their guess and $($assuming no errors$)$ will forward

the guess to the server thread via the output stream of the socket. Once a guess has been

received on the server side, the server will respond by providing an indication of how close the

guess was. The server encodes its response by reporting a combination of $4$ of the following

values. P $($correct color and position$),$ C $($correct color wrong position$),$ or a string of $4$ blanks

indicating neither correct color nor correct positions were found. For example, suppose the

program chose the code RGGW $($red$,$ green, green, blue$).$ If the user were to guess WBGG then

the program would respond with $$CCP$\_$ indicating that two of the guessed pegs are correct in

color but not position and a third peg is both the correct color AND in the correct position. Note

that the $\_$ represents a blank space. All replies from the server will consist of a $4$ character

string. If the server thread is ever sent a correct guess, then it will reply with the string $"$PPPP$"$

and will cease its execution. When the client receives the $"$PPPP$"$ string it will report the win to

the user along with the total number of guesses that the user provided during the game.
