A corporation has six divisions, each responsible for sales of different geographic locations. The DivSales class holds the quarterly sales data for one division. Complete the  DivSales class which keeps sales data for  one division, with the following members: sales - a private array with four elements of type double for holding four quarters of sales figures for one division. (Note this is not a dynamic array). This is provided. totalSales - a private static variable of type double for holding the total corporate sales for all the divisions (every instance of DivSales) for the entire year. a default constructor that sets all the quarters to 0 . This is provided. setSales - a member function that takes four arguments of type double, each assumed to be the sales for one quarter. The value of each argument should be copied into the private sales array. The total of the four arguments should be added to the static variable totalSales that holds the total yearly corporate sales. If a sales value is < 0, set the value to 0. getQSales - a constant member function that takes an integer argument in the range of 0 to 3. The argument is to be used as a subscript into the quarterly sales array. The function should return the value of the array element that corresponds to that subscript or return 0 if the subscript is invalid. getCorpSales - a static member function that returns the total corporate sales Download the file DivSales_startfile.cpp and use this as your start file. The start file creates a  divisions array of six  DivSales objects that are each initialized with the default constructor. The default constructor is already implemented for you. Below is the quarterly sales data for the six divisions. Your program should populate the  divisions array with the following data set  using the setSales method of your class. 3000.00, 4000.00, 5000.00, 6000.00 3500.00, 4500.00, 5500.00, 6500.00 1111.00, 2222.20, 3333.30, 4444.00 3050.00, 4050.00, 5050.00, 6050.00 3550.00, 4550.00, 5550.00, 6550.00 5000.00, 6000.00, 7000.00, 8000.00 DO NOT PROMPT FOR USER INPUT IN THIS PROGRAM. Use your  setSales method with the data set above to set the values of each object in the divisions array. After the six objects are updated, the program should display the quarterly sales for each division with labels. The program should then display the total corporate sales for the year.
