Design a class named Record that includes

A data member named rollNo for student roll number

Two data fields i.e. course1Name and course2Name of type string

A parameterized constructor to initialize rollNo, course1Name, and course2Name data fields

Three getter functions to get the value of rollNo, course1Name, and course2Name, respectively

Derive a class named CourseRecord inherited from Record class and contains

Two additional data members i.e. marksCourse1 and marksCourse2

A parameterized constructor to initialize its own data fields along with the inherited data fields

Two getter functions that return the value of marksCourse1 and marksCourse2, respectively

Derive a class named CourseResult inherited from class CourseRecord and has

A data field named totalMarks

A function named marksObtained that returns totalMarks (i.e. marksCourse1 + marksCourse2) of a

student

A member function named display to show rollNo, course1Name, course2Name, marksCourse1,

marksCourse2, and totalMarks

Create main() to check the operability of the code.
