Don't attempt if you can't attempt fully, i will dislike a nd negative comments would be given Please it's a request. c++ We will read a CSV files of a data dump from the GoodReads 2 web site that contains information about user-rated books (e.g., book tit le, publication year, ISBN number, average reader rating, and cover image URL). The information will be stored and some simple statistics will be calculated. Additionally, for extra credit, the program will create an HTML web page based on the top n highest rated books. As is typical of many subject matter information sources, the data in the file contains various errors. As such, we will track the errors and create an exceptions files to track the lines with data errors. Develop a class, bookDataType, to provide functionality for reading and storing book information. The UML class specifications are provided below. A main will be provided that uses the bookDataType class. ● Book Data Type Class The class will implement the functions. bookDataType -COL_LIMIT = 23: static constexpr unsigned int -TOP_LIMIT = 20: static constexpr unsigned int -booksFileName: string -webPageFileName: string -exceptionsFileName: string -bookCount: unsigned int 1 For more information, refer to: https://en.wikipedia.org/wiki/Comma-separated_values 2 See: www.goodreads.com-topBooksLimit: unsigned int -*topBooks: unsigned int -struct bookErrsStruct -bookIDErrors: unsigned int -bookYearErrors: unsigned int -AveRatingErrors: unsigned int -duplicateDataErrors: unsigned int -bookErrInfo: bookErrsStruct -struct bookStruct -bookTitle: string -isbn: string -pubYear: short -aveRating: float -imageURL: string -bookID: unsigned int -*bookInfo: bookStruct +bookDataType() +~bookDataType() +getBookArguments(int, char *[], string &, bool &): bool +getBookFileName() const: string +getWebPageFileName() const: string +getExceptionsFileName() const: string +getReadBookIDErrors() const: unsigned int +getReadBookYearErrors() const: unsigned int +getReadBookAveRatingErrors() const: unsigned int +getReadBookDuplicateErrors() const: unsigned int +getTopBooksLimit() const: unsigned int +showBookData(unsigned int) const: void +getBookCount() const: unsigned int +getAverageOverallRating() const: float +showHighestRatedBooks() const: void +readBookData(const string): bool +buildWebPage(const string="CS 202 Top Books") const: bool +findHighestRatedBooks(): void +setWebPageFileName(const string): void +setExceptionsFileName(const string): void +setTopBooksLimit(unsigned int): void -parseLine(string, string []) const: void Note, points will be deducted for insufficient commenting, poor style, or inefficient coding. The error messages should be prefixed with the function name (to help better identify the source of the error). Refer to the sample execution for error message examples.Function Descriptions • The bookDataType() constructor should set the books filename to the empty string, the bookCount to 0, the topLimit to a default value of 5, the error counts to 0, the web page file name to a default value of “index.html”, and the exceptions file to a default value of “errors.txt”, and the pointers to the nullptr. • The ~bookDataType() destructor should delete the dynamically allocated arrays, set the other class variables to their default values (noted above). • The getBookArguments() function should read the command line qualifiers in the required format ( -i [<-show|-noshow>] ) to obtain the file name and set the show extra information flag (true/false). The data file and show extra flag may be in either order. The show extra flag is optional and the “-noshow” is the default if not specified. This includes a usage message and error messages for both the input file specifier and the input file name. The file name must be at least one letter and include a “.csv” extension (thus, the minimum length is 5). If the file name is incorrect or does not exist, an appropriate error message should be displayed, the class variable should remain unchanged, and the function should return false. To determine if a file exists (without opening it), you can use the access() function (i.e, ( access(fn.c_str(), F_OK) ) which returns a 0 if the file exists and returns a -1 if the files does not exist. Note, the access() function requires the #include statement. If there is an error, the function should output one of the following error messages: cout cout cout cout cout • • • • • • • • • << << << << << "Usage: "Error, "Error, "Error, "Error, ./books -i [<-show|-noshow>]" << endl; invalid input file name specifier." << endl; invalid command line options." << endl; book data file name must be '.csv' extension." << endl; invalid show extra information specifier." << endl; based on the specific error. The getBookFileName() function should return the current book file name. The getWebPageFileName() function should return the current web page file name. The getReadBookIDErrors(), getReadBookYearErrors(), getReadBookAveRatingErrors(), and getReadBookDuplicateErrors() functions should return the applicable structure field. The getExceptonsFileName() function should return the current exceptions file name. The setBookFileName() function should set the class variable for the books file name to the passed file name. The file name must be at least one letter and include a “.csv” extension (thus, the minimum length is 5). If the passed file name is correct and the file exists, the class variable should be set and a true returned. If the file name is incorrect or does not exist, an appropriate error message should be displayed, the class variable should remain unchanged, and the function should return false. To determine if a file exists (without opening it), you can use the access() function (i.e, ( access(fn.c_str(), F_OK) ) which returns a 0 if the file exists and returns a -1 if the files does not exist.. The setWebPageFileName() function should set the class variable for the web page file name to the passed file name. The file name must be at least one letter and include a “.html” extension (thus, the minimum length is 6). The setExceptonsFileName() function should set the class variable for the file name to the passed file name. The file name must be at least one letter and include a “.txt” extension (thus, the minimum length is 5). The getTopBooksLimit() function should return the value for the current number of highest rated books to be found. The setTopBooksLimit() function should set the class variable for the current number of highest rated books to be found. The value must not exceed the TOP_LIMIT constant. If the passed value is out of range, nothing should be changed.• • • The getBookCount() should return the current number of books in the data set. The getAverageOverallRating() function should return the overall average of book rating in the entire current data set. The showBookData() function should display the formatted book information to the screen in the specified format (see output example). cout cout cout cout cout cout cout • • • • • << << << << << << << "Book Information:" << offset << "Title: " offset << "Book ID " offset << "ISBD: " offset << "Year: " offset << "Ave Rate: " endl; endl; << bookInfo[idx].bookTitle << endl; << bookInfo[idx].bookID << endl; << bookInfo[idx].isbn << endl; << bookInfo[idx].pubYear << endl; << bookInfo[idx].aveRating << endl; The showHighestRatedBooks() function should show the topBooksLimit number of highest rated books using the showBookData() function from the topBooks array. As such, the findHighestRatedBooks() function must have been previously called. The findHighestRatedBooks() function should find the topBooksLimit number of highest rated books. This will require dynamic creation and population of the topBooks[] array of topBooksLimit size. The array will hold the index of the book into the bookInfo[] array. Due to the data size, a sort is not appropriate. The topBooksLimit number of highest rated books should be determined with out performing a sort. The parseLine() function will accept a string in comma-separated format and break the string into its individual comma separated fields. This includes handling quoted fields that may contain commas which are not field separators when inside quotes. The function should populate the passed array with the COL_LIMIT fields in string format. If the line contains more than COL_LIMIT fields, only the first COL_LIMIT should be returned (thus, do not over-write the array). The readBookData() function should read the books file (CSV format). This function will call the private parseLine() function. From the returned string array, the following fields should be placed into the applicable fields of bookInfo[] array. • Book title (first title), string ◦ note, of first title is empty, use second title • ISBN (10 digit), string • ImageURL (first of two), string • Publication Year, short • Book ID (good reads book ID, which is first), unsigned integer • Average Rating, float Note, since some data field may be invalid, try/catch blocks must be used for the conversion. The first line is a header line and must be skipped. Blank lines should be skipped. In order to size the bookInfo[] struct array, you will need to read the file twice; once to count the data lines and again to read the data. To reset the file to the beginning, use inFile.clear(); followed by inFile.seekg(0, ios::beg); . To convert string values into floats or integers, use the stoi() and stof() functions. In order to check for errors, these should be performed within a try/catch block. Errors should be written to the exceptions file with a line of 60 ‘-’s, the specific error, the line number (from the source data file), and on the next line the title “Row Data:”, and on the next line the complete row followed by a blank line. Refer to the examples for formatting. Duplicate rows are determined by the same book ID number and the second occurrence written to the exceptions file. See examples for formatting. EXTRA CREDIT (up to 25 pts) → The buildWebPage() function should build an HTML web page of the top topBooksLimit number of highest rated books including a link to the image and the book information on the GoodReads web site. The Good Reads link is generated by appending the book ID to the URL" https://www.goodreads.com/book/show/ " within an HREF tag along with the title. For example, The Complete Calvin and Hobbes for book ID 24812. The passed string is the web page title (using CS 202 Top Books Page in the header block) and the initial we page label (using an title tag) with a subtitle of “Top Rated Books” (using an subtitle tag). The minimum requirements for the web page include the title and subtitle headers, followed by the books. The books must be numbered (1, 2, ...), include the good reads book information link, the book cover image, the ISBN number (10 digit), and the book average rating. See the provided example for a minimal required format. The full 25 points will only be awarded if the final web page exceeds the minimal formatting (see example). Refer to the example executions for output formatting. Make sure your program includes the appropriate documentation. See Program Evaluation Criteria for CS 202 for additional information. Make File: You will need to develop a make file. You should be able to type: make Which should create the executable. The makefile will be very similar to the previous assignment makefiles. Submission: ● Submit a zip file of the program source files, header files, and makefile via the on-line submission. All necessary files must be included in the ZIP file. The grader will download, extract, and type make (so you must have a valid, working makefile). CSV Format Fields in a CSV file are comma-separated. Typically (but not always), the first line of the file contains a row showing the field names. This is the case for our data files. A field may contain a number or may be quoted (that is, enclosed within double-quote characters) indicating string fields such as book titles. Such strings (names/titles) may have embedded commas and embedded quote characters (which must be double-quoted). For example, ,"J.K. Rowling, Mary GrandPré, Rufus Beck", ,"A Child Called ""It"": One Child's Courage to Survive", ,"""M"" is for Malice", ,"""Who Could That Be at This Hour?""", The double-quotes are used to mark a string field and are not actually part of the string. For example, the first line (above) is actually J.K. Rowling, Mary GrandPré, Rufus Beck . Where the double-quotes mark only the start and end. Since the double-quote is used to mark the start and end of a field, a double double-quote is used to signify an actual double-quote. For example, the second line is A Child Called "It": One Child's Courage to Survive , the second line is "M" is for Malice , and the third line is "Who Could That Be at This Hour?" .These requirements can make the reading of CSV files a challenge. In addition, may data sources in CSV format have imperfect data with various errors include invalid numeric values, too few fields, or too many fields. Try/Catch Block Example Below is an example of how to use the try/catch block for conversion using the C++ stoi() function. unsigned int unsigned long string try { someNumber = 0; size = 0; badNum = "12-34"; someNumber = stoi(badNum, &size); if (size != columns[8].size()) throw invalid_argument("Conversion Error"); } catch (exception &err) { errFile << err.what() << endl; }
