Due: Tuesday October 30 2018 before 11:59 PM Email-based help Cutoff: 5:00 PM on Sun, Oct 21 2018Maximum Points:  30Submission InstructionsOS Systems代写This homework assignment must be turned-in electronically via Canvas CODE plug-in. Ensure your C++ source code is named MUID_hw6.cpp, where MUID is your Miami University Unique ID. Ensure your program compiles without any warnings or style violations. Ensure you thoroughly test operations of your program as indicated. Once you have tested your implementation, upload the following:The 1 C++ source file developed for this homework.General Note: Upload each file associated with homework individually. Do not upload archive file formats such as zip/tar/gz/7zip/rar etc.ObejectThe objective of this homework is to:A multithreaded C++ program (synchronization is notneeded)Continue to gain familiarity with use of HTTP protocol forcommunicationContinue to gain familiarity with I/O streams stringprocessingGrading Rubric:The program submitted for this homework must pass necessary base case test(s) in order to qualify for earning any score at all. Programs that do not meet base case requirements will be assigned zero score!Program that do not compile, have a method longer than 25 lines, or just some skeleton code will be assigned zero score.See points set for each command and overall structure, organization, conciseness, variable-names, etc. in the next page.If your methods are not concise points will be deducted.-1 Points: for each warning generated by the compiler (warnings are most likely sources of errors in C++programs)NOTE: Violating CSE programming style guidelines is an error! Your program should not have any style violations. Problem summaryDevelop a multithreaded C++ program that uses multiple threads to process a list of URLs specified as command-line arguments. For each URL, the program must print (in the same order in which URLs are specified) the number of words, and number of valid English words. A dictionary is supplied to determine valid English words.Starter codeStarter code is provided to streamline the following operations for you. You should study these methods and be able to explain what these methods do –Load valid English words from a given dictionary file (see:loadDictionary)Determine if a given word is a valid English word (see:isValidWord)A simple method to change punctuations and special characters to spaces to ease extracting/processing words in a line of data (see:changePunct)Program InputsThe program must use command-line arguments for obtaining inputs. The command line arguments will be in the following format:The first command-line argument will specify the number of threads to use. For base case requirements, the number of threads will be 1. For other cases the number of threads will vary, but will always be lower than the number ofURLsRest of the command-line arguments will be 1-or-more files to retrieve. Each file need to be added to a base URLhttp://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=.   For   example, given a file html, the full URL will be: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html.Program OutputsThe result of processing URLs should be displayed in exactly the same order in which the URLs were specified. For each URL, the program should generate 1 line of output, in the following format: URL ,☐words:☐ #Words ,☐English☐words:☐ #EngWords , whereis 1 blank space. Strings in blue are literal constants. See sample outputs forSample inputs and outputsThe command typed in is shown in bold. The commands and outputs are long because of URLs and have been wrapped in this document; however, they are on one single line. Video on setting command-line arguments in NetBeans is available on Canvas.Base cases [12 points]$ ./homework6 1 ex3.htmlURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16./homework6 1 ex3.html cpp.txtURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=cpp.txt, words: 6983, English words: 5810$ ./homework6 1 ex3.html cpp.txt us_constitution.txt miami_university.txtURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=cpp.txt, words: 6983, English words: 5810URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=us_constitution.txt, words: 7667, English words: 7422URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=miami_university.txt, words: 32331, English words: 15348Multi threading tests (change number of threads, but exact same outputs) [18 points]$ ./homework6 2 ex3.html cpp.txt us_constitution.txt miami_university.txtURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=cpp.txt, words: 6983, English words: 5810URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=us_constitution.txt, words: 7667, English words: 7422URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=miami_university.txt, words: 32331, English words: 15348$ ./homework6 3 ex3.html cpp.txt us_constitution.txt miami_university.txtURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=cpp.txt, words: 6983, English words: 5810URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=us_constitution.txt, words: 7667, English words: 7422URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=miami_university.txt, words: 32331, English words: 15348$ ./homework6 4 ex3.html cpp.txt us_constitution.txt miami_university.txtURL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=ex3.html, words: 39, English words: 16URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=cpp.txt, words: 6983, English words: 5810URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=us_constitution.txt, words: 7667, English words: 7422URL: http://ceclnx01.cec.miamioh.edu/~raodm/SlowGet.cgi?file=miami_university.txt, words: 32331, English words: 15348It is easiest to store the files specified as command-line arguments into a vector to further processUse the simple HTTP client example from lecture slides to obtain response from the server.Extracting words and counting valid English is straightforward usinganistringstream. Don t over complicate this part.Approach this problem as a data parallel application in which a subset of URLs is assigned to a thread to process. The logic of assigning threads to URLs is almost a copy- paste from lectureIn continuation with examples from lecture slides, it would be easiest to store results as a string in another vector and then finally print the vector after all the threads have finished running.If you find your program running too slowly in NetBeansyou can use the Release mode (instead of Debug)Submit to CanvasThis homework assignment must be turned-in electronically via Canvas CODE plug-in.
