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
