processing system using inheritance. Assume that student is the base class and holds the register number of the student. The class 'test' extends the student class.

The test class has marks of the five subjects for the student. Each student has taken two tests. The class 'sports' also extends the student class and holds the sports class score of the student.

Calculate the total marks for the student - Sum of five subject marks for the two tests and the sports mark and display the marks. Use constructors for initializing variables.
