- Open the Calories Solution.sln file contained in the VB2017\Chap08\Calories Solution folder. Open the Code Editor window and locate the btnDisplay_Click procedure. The procedure declares and initializes a one-dimensional array named intCalories. The array stores the numbers of daily calories consumed. The procedure should calculate and display the average number of calories consumed; use the Math.Round method to round the average to an integer. (You learned about the Math.Round method in Chapter 6.) The procedure should also display the number of days in which the daily calories were greater than the average, the number of days in which the daily calories were the same as the average, and the number of days in which the daily calories were less than the average.
