This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A Step Tracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active The StepTracker class provides a constructor and the following methods • add DailySteps, which accumulates information about steps, in readings taken once per day activeDeys, which returns the number of active days • averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results.
