Write a Program to design a stuent class representing student roll no. and a test class (derived class of student) representing the scores of the student in various subjects and sports class representing the score in sports. The sports and test class should be inherited by a result class having the functionality to add the scores and display the final result for a student.

#include<iostream.h>
class student
{
protected:
int roll_number;
public:
void get_number(int a)
{
roll_number = a;
}
void put_number(void)
{
cout<<"Roll No:"<<roll_number<<"\n";
}
};
class test : public student
{
protected:
float part1, part2;
public:
void get_marks(float x, float y)
{
part1 = x;
part2 = y;
}
void put_marks(void)
{
cout<<"Marks obtained"<<"\n"<<"part1 ="<<part1<<"\n"<<"part2 ="<<part2<<"\n";
}
};
class sports
{
protected:
float score;
public:
void get_score(float s)
{
score = s;
}
void put_score(void)
{
cout<<"Sports wt:"<<score<<"\n\n";
}
};
class result : public test, public sports
{
float total;
public:
void display(void);
};
void result ::display(void)
{
total = part1 + part2 + score;
put_number();
put_marks();
put_score();
cout<<"Total Score:"<<total<<"\n";
}
int main()
{
result student_1;
student_1.get_number (1234);
student_1.get_marks (27.5, 33.0);
student_1.get_score (6.0);
student_1.display ();
return 0;
}
