A teacher wants to maintain the attendance for the classroom. After storing the attendance, he wishes to print the details of the top 3 attendance percentage holders. Create a class with the private data members: name (string), roll_no (integer), percent (float). Create a constructor which will initialize name with NULL, roll_no with 0 and percent with 0.0. Public data members: A function get_details() – which will accept all the details from the user, a function show_details() – which will display all the details. Define another function called get_attendance() which will return the attendance of the calling object. Using the get_attendance() function, get the attendance and sort the records in descending order.
Show the details of the top 3 attendance percentage holders by invoking the
show_details() function. Define a destructor which prints “Objects destroyed successfully”.
