Create a class Student with following data members- name, roll no and marks as private data member. Create array of objects for three students, compare their marks using operator overloading, and display the records of the student who is getting highest score. 

Create a class Employee with the data members such as name, id and total salary. Create a file as "Employee_Data" as binary file and write the information of four employees to that file. Open that file in reading mode and only display the record of 2nd and 3rd employees.

Create a class Employee with following data members, name, id, and salary as private data member. Create array of objects for four employees, compare their salary using operator overloading, and display the records of the student who is getting less salary.

Suppose, the same function is defined in both the derived class and the based class. Now if we call this function using the object of the derived class. Compiler will call which function and elaborate the same used by the compiler.

1.      >>> 2- 2

2.      >>> 2 -(2-)

 File "<stdin>", line 1

   2 -(2-)

         ^

SyntaxError: invalid syntax

3.      >>> (0+1)-9(1/2)

<stdin>:1: SyntaxWarning: 'int' object is not callable; perhaps you missed a comma?

Traceback (most recent call last):

 File "<stdin>", line 1, in <module>

TypeError: 'int' object is not callable

Give explanation to these results experimented in python.

There are following two major issues associated with cpp programs:

• When a program is terminated, the entire data is lost.
• If you have to enter a large number of data, it will take a lot of time to enter them all in
• the different programs.

Suggest a solution and elaborate the same with the help of suitable examples 

Create a class: “Palindrome” with private data members: upper_limit (int), lower_limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of palindrome numbers from upper_limit to lower_limit. [Example: upper_limit:50, lower_limit:10, count of palindrome numbers is: 4(11 , 22, 33 and 44), also make sure the value of upper_limit should be greater than lower_limit].
