The Person class is depicted in Figure $1.$

As indicated in the class diagram, each person object contains the PRIVATE fields ID$,$ name, and age. The data members ID and age are integers, and the name is a string. The class includes public mutators, accessors, constructors, and a toString$()$ user$-$defined function that returns a string indicating the fields held in the object $($see slides chapter $13).$

Write an app to implement the Person class. The app will create a database of Person objects. The database should be represented as vector $$ Person $>db.$

The data to create the vector is stored in the file c:$/$temp$/$springfieldPeople$.$txt $($see Figure $2).$ Each file record consists of id$,$ name, age, and data $($Caution $-$ Not each of those fields will be used to make a person instance.$)$

Your app must include a function called printYoungPeople. This function will identify and display the persons whose age is less than the calculated average age of the sample.

Figure $1.$ Class Diagram

The function's header is provided below.

void printYoungPeople$($vector $$ Person $>$&$db)$

For instance, if you calculate the average age and it produces a value such as $40,$ the printYoungPeople function will display those individuals strictly under $40.$ Displaying the selected person objects must be done using the toString method.
