ALGORITHM:

Step 1: Start the program.
Step 2: Declare the base class student.
Step 3: Declare and define the functions getnumber() and putnumber().
Step 4: Create the derived class test virtually derived from the base class student.
Step 5: Declare and define the function getmarks() and putmarks().
Step 6: Create the derived class sports virtually derived from the base class student.
Step 7: Declare and define the function getscore() and putscore().
Step 8: Create the derived class result derived from the class test and sports.
Step 9: Declare and define the function display() to calculate the total.
Step 10: Create the derived class object obj.
Step 11: Call the function get number(),getmarks(),getscore() and display().
Step 12: Stop the program.

PROGRAM:

#include<iostream.h> #include<conio.h>   class student {    int rno;   public:    void getnumber()    {               cout<<"Enter Roll No:";               cin>>rno;    }    void putnumber()    {               cout<<"\n\n\tRoll No:"<<rno<<"\n";    } };   class test:virtual public student {     public:    int part1,part2;    void getmarks()    {               cout<<"Enter Marks\n";               cout<<"Part1:";               cin>>part1;               cout<<"Part2:";               cin>>part2;    }    void putmarks()    {               cout<<"\tMarks Obtained\n";               cout<<"\n\tPart1:"<<part1;               cout<<"\n\tPart2:"<<part2;    } };   class sports:public virtual student {     public:     int score;     void getscore()     {               cout<<"Enter Sports Score:";               cin>>score;     }     void putscore()     {               cout<<"\n\tSports Score is:"<<score;     } };   class result:public test,public sports {     int total;   public:    void display()    {       total=part1+part2+score;       putnumber();       putmarks();       putscore();       cout<<"\n\tTotal Score:"<<total;    } };   void main() {    result obj;    clrscr();    obj.getnumber();    obj.getmarks();    obj.getscore();    obj.display();    getch(); }

Output:

Enter Roll No: 200
Enter Marks
Part1: 90
Part2: 80
Enter Sports Score: 80
Roll No: 200
Marks Obtained
Part1: 90
Part2: 80
Sports Score is: 80
Total Score is: 250
