Write a C++ program to prompt the user to input N
positive integers; when the user enters - 1 the
program input will stop and implement the needed
functions (5 points)
• Function to calculate the count of input positive
number.
(5 points)
• Function to calculate the average of even
integers
(5 points)
• Function calculate the max of odd
integers
(5 points)
• Function calculate the sum of integers <=
(5 points)
Output the result of the above
operations

50
HINT
1- Functions should be called by Value
2- Functions should return a value to be used for output in final point.

8. create an abstract student class for parker university. the class contains fields for student id number, last name, and annual tuition. include a constructor that requires parameters for the id number and name. include get and set methods for each field; the settuition() method is abstract. create three student subclasses named undergraduatestudent, graduatestudent, and studentatlarge, each with a unique settuition() method. tuition for an undergraduatestudent is $4,000 per semester, tuition for a graduatestudent is $6,000 per semester, and tuition for a studentatlarge is $2,000 per semester. write an application that creates an array of at least six objects to demonstrate how the methods work for objects for each student type. save the files as student.java, undergraduatestudent.java, graduatestudent.java, studentatlarge.java, and studentdemo.java.
