This assignment asks you to implement simple client$-$server application. This application is a slightly extension of the daytime client$-$server application. Specifically, there are two processes in this application, a client and a server. $(1)$ The client process is waiting in a loop for an input string from standard input. For each input string, the client simply sends it to the server process. Then the client waits for a reply from the server. After receiving a reply, it will print out the reply, and go back to waiting for an input string. $(2)$ The server process, similar to the server process in daytime application, is waiting at an accept statement. After accepting a connection, it will read an input string. For each input string, it will execute it as a command and send the result of the excuetion back to the client. Please follow the submssion instructions for format and required documents. For each programming problem, the actual programs, together with any supplementary files, must be submitted. You cannot simply submit a text$/$word file for programming problems. The programming language must be C$++.$ No other languages allowed.
