Question

Any little bit of information will be helpful. Thank you.

Problem Statement You are to develop a program to read MotoGP rider information from an input file. You will need a MotoGpRider class whose instances will be used to store the statistics for a MotoGP motorcycle racer. The Rider class will have attributes for last name, first name, racing number, nation, motorcycle make, world championship points, world championship position, and an array that stores the number of top finishes (number of 1" place finishes, number of 2 place finishes, and number of 3d place finishes). You must read the MotoGP rider information from an input file. Each line of the input file will contain single rider's name and information, in the order the information is listed above. All information on the line will be separated by spaces. a Operations for the MotoGpRider class: Provide a default constructor o default string values are "unknown" o default integer values are 0 Read a rider from a single line of the file (The input file should be passed to the read method. You will need to pass it by reference.) Get methods for any data the test driver might need to print later A method to calculate the total number of top 3 finishes A method to return the rider's full name (first name followed by last name) A method to print the rider information to an output file (output file should be passed to the print method) To store multiple MotoGP riders, you are to implement a RiderList data structure/data type that stores riders using an internal array in the class. Read each rider from the input file and then add to the list. Your RiderList structure should hold a maximum of 10 riders. You must track the number of riders actually stored in the list, since the data file could contain fewer or greater than 10 riders. You will need to make sure the list is not full before adding a new rider. You may assume there are no errors in the data. I will not leave data out or put non-numeric data in numeric fields. You must implement the following operations on your List along with any other utility functions you might need. You may also need to add operations to your rider to encapsulate i/o operations to the class. Operations for the RiderList class: Default Constructor - initialize the number of riders to 0 Add a rider to the List-add items in the order they were found in the file. No sorting is necessary in this version of the program. Iterate through the List so that you can get each item out for printing You must implement reset(), hasNext() and getNext() on your list for this to work. Clear out the list to make it empty Test if a list is Full Get the size of the list Sample Input File and Corresponding Output File sample input text file Rossi Valentino 46 Italy Yamaha 198 3 0 1 4 Marquez Marc 93 Spain Honda 321 1 9 4 1 Dovizioso Andrea 4 Italy Ducati 245 2 4 32 Vinales Maverick 12 Spain Yamaha 1934 113 Note-there should be NO blank lines after the last line of data in an input file. sample output text file 2018 World Championship Statistics RIDER NAME NUMBER POINTS POSITION Valentino Rossi: 46 198 Marc Marquez : Andrea Dovizioso: Maverick Vinales: 93 321 245 12 193 4 RIDERS Valentino Rossi Number Motorcycle : 46 : Yamaha : Italy Top 3 Finishes: 5 Nation Marc Marquez Number 93 Honda : Spain Motorcycle Nation Top 3 Finishes: 14 Andrea Dovizioso Number Motorcycle Nation : 4 : Ducati : Italy Top 3 Finishes: 9 Maverick Vinales : 12 Number a Motorcycle Nation : Spain Top 3 Finishes: 5
