This class should have the following member functions:

$$ Create a constructor with no parameters that increments the static variable by $1$ and

assigns it to the roll number. The remaining data members should be initialized to zero

or empty values.

$$ Input$()$ function that will allow the user to input the names and marks of $5$ courses.

$$ Show$()$ function that will display the roll number, name and marks of $5$ courses to

the user.

$$ TotalStudents$()$ function that should display the number of objects that have

been created so far. This function should be static.

$$ TotalMarks$()$ function that should calculate and return the total marks of a

student.

$$ getHighest$()$ function that returns the highest mark of the student.

$$ getLowest$()$ function that returns the lowest mark of the student.

$$ getAverage$()$ function that returns the average mark of the student.

$$ getPassCount$()$ function that counts and returns the total number of courses in

which the student has passed $($a student passes the course if he$/$she gets a mark

between $50$ and $100$; fails the course if he$/$she gets a mark between $0$ and $49.)$

In the main function, create three objects, input their values and display them. For each

student, display the student$$s total marks, highest mark, lowest mark, average mark,

and the number of courses which he$/$she passed. Also display how many students have

been registered so far $($i$.$e$.$ the number of objects$).$ Every student must write his$/$her real

name and surname and student id number in the first object. You may use fictional

names and surnames in the following two objects.
