Clinet & Server - Socket programming

Client.c: The code should send one specific filename to the server and print out the results returned from the server. Server.c: The code should receive one specific filename from client and starts calculating the next higher number of each number in that file using multi-threading. At the end, the program should sum up all the next higher numbers and return the final results to the connected client. Compile these two codes separately into two executable files called server and client. PS: I'll provide you with the code for "next higher number of each number in the file using multi-threading", you just need to implement the above mentioned steps.
