Write a full class definition for a class named Averager, and containing the following members:An data member named sum of type integer. An data member named count of type integer. A constructor with no parameters. Theconstructor initializes the data members sum and the data member count to 0.A function named getSum that accepts noparameters and returns an integer. getSumreturns the value of sum. A function named add that accepts an integer parameter and returns no value. add increases the value of sum by the value of theparameter, and increments the value of countby one. A function named getCount that accepts noparameters and returns an integer. getCountreturns the value of the count data member, that is, the number of values added to sum. A function named getAverage that accepts noparameters and returns a double. getAveragereturns the average of the values added to sum. The value returned should be a value of type double (and therefore you must cast the data members to double prior to performing the division).
