Programming Assignment

need it in 3 hours properly commented Submission: In this assignment, using sockets and PThreads, you implement a server that calculates the factorial of numbers (n!). When the connection is established between the client and the server, the server sends a “READY” message to the client using the already established connection. The client then sends the number for which it would like to compute the factorial. The server calculates the factorial and returns it to the client. In order to be able to count the number of clients already served, a specific PThread receives signals from all PThreads who serve clients. Those PThreads send a signal when they send the request back to the client before they terminate. When the counter PTreads receives a signal from another PThread, it increments a counter then prints it. When the number of served clients reaches a certain number (10 for example), the server terminates all threads while printing the number of served clients and for how much time it has been running. Guidelines: Please observe the following guidelines while writing your programs: • All errors should be written to the error stream • Use appropriate names of variables • Make good and appropriate use of functions • Use appropriate names of functions • Provide enough comments to understand your code • Use appropriate indentations
