MULTILEVEL INHERITANCE

AIM:
         To implement a C++ program to find out the student details using multilevel inheritance.

ALGORITHM:

Step 1: Include the header files

Step 2: Declare the base class student.

Step 3: Declare and define the function get_ number ( ) and put_number( ).

Step 4: Declare the derived class test for student

Step 5: Declare and define the function get_ marks ( ) and put_marks( ).

Step 6: Declare the derived class result for test

Step 7: Declare and define the function display ( )

Step 8: Create objects for the derived class.

Step 9: Declare the derived class object, call the functions get_ number ( ), get_ marks ( ), display ( ).

PROGRAM:

#include<iostream.h>

#include<conio.h>

class student

{

protected:

 int roll;

public:

 void get_number(int a)

 {

  roll = a;

 }

  void put_number()

 {

  cout<<"Roll Number: "<<roll<<"\n";

 }

};

class test : public student

{

protected:

 float sub1;

 float sub2;

public:

 void get_marks(float x,float y)

 {

  sub1 = x;

  sub2 = y;

 }

 void put_marks()

 {

  cout<<"Marks in Subject 1 = "<<sub1<<"\n";

  cout<<"Marks in Subject 2 = "<<sub2<<"\n";

 }

};
