Q8- Change the client program code with name "labl4q8_client.c" such that user enters 2 inputs: A floating point number for the temperature value A character: Either C of F for the temperature type Also, change the server code with name "lab I 4q8_server.c" such that: if the character received was C it should convert the floating point number from Celsius to Fahrenheit, and if F then it should go vice versa. Then, the server should send the proper message to the client side, either: Server: Temperature in x Celsius = y Fahrenheit Or, Server: Temperature in x Fahrenheit = y Celsius Finally, the server closes the connection and loop back for a new client. The program should check and report properly with clear messages for any system errors in both the client and server programs. a- Include the source files in your report.

b- Show the commands to compile and link them with the names "labl4q8_client" and "labl4q8_server".

c- Open two terminals and do the following:

First terminal: execute the server program like:

./labl4q8_server 2222

Second terminal: execute the client program like:

./ lab14q8_client 127.0.0.1 2222

Test the client/server exchange of messages. Show three run outputs in your report for two correct cases ( C and F) and one wrong client request format.
