Hybrid Inheritance

There could be cases where we need to apply more than two types of inheritances to design a program. when we apply two or more types of i inheritances n a single program then it is called a hybrid inheritance.

For Example :We wanted to write a simple program that could perform processing of students results.

Program:

#include<iostream>

using namespace std;

class student

{

 protected:

   int rollno;

   char name[30];

 public:

   void getdata()

   {

    cout<<"\nEnter student's Name:";

    cin>>name;

    cout<<"enter the rollno:";

    cin>>rollno;

   }

  void display_details()

  {

   cout<<"\nName:"<<name;

   cout<<“\nRoll no:"<<rollno;

  }

};

class test: public student

{

 protected:

  float sub1,sub2;

 public:

 void get_marks()

 {

  cout<<endl<<"student subject 1=";

  cin>>sub1;

  cout<<"subject 2=";

  cin>>sub2;

 }

 void disp_marks()

 {

  cout<<“\nSubject 1="<<sub1;

  cout<<"\nSubject 2="<<sub2;

 }

};

class sports

{

 protected:

  float score;

 public:

  void get_score()

  {

   cout<<"\nEnter the score:";

   cin>>score;

  }

  void disp_score()

  {

   cout<<endl<<"score="<<score;

  }

};

class result:public test,public sports

{

  float total;

 public:

  void display()

  {

   display_details();

   disp_marks();

   disp_score();

   total=sub1+sub2+score;

  cout<<"\nTOTAL score="<<total;

  }

};

int main()

{

 int n;

 cout<<"Enter the number of students:";

 cin>>n;

 result s[70];

 for(int i=0;i<n;i++)

 {

  cout<<"\nSTUDENT NO:"<<i+1;

  s[i].getdata();

  s[i].get_marks();

  s[i].get_score();

}

 cout<<endl<<endl;

for(int i=0;i<5;i++)

 {

  cout<<"\nSTUDENT NO:"<<i+1;

  s[i].display();

}

  return 0;

}
