1. Simple Inheritance.
Code:
#include<iostream>
#include<conio.h>
#include<stdio.h>
using namespace std;
class student
{
protected:
int Roll_No;
char name[20];
char branch[10];
public:
void getData()
{
cout<<"Enter the name:
";
cin.getline(name,20);
cout<<"Enter the Branch
:";
cin.getline(branch,10);
cout<<"Enter the Roll_No :
";
cin>>Roll_No;
}
};
class test : public student
{
private:
float marks;
public:
void getMarks()
{
getData();
cout<<"\nEnter the Marks
:";
cin>>marks;
}
void show()
{
cout<<"\nName
:"<<name;
cout<<"\nRoll No.
:"<<Roll_No;
cout<<"\nBranch :"<<branch;
cout<<"\nMarks
:"<<marks;
}
};
int main()
{
test t;
t.getMarks();
t.show();
}
2.Multiple
Inheritance
Code:
#include<conio.h>
#include<iostream>
#include<stdio.h>
using namespace std;
class student
{
protected:
int Roll_No;
char name[20];
public:
void getData()
{
cout<<"Enter the Name :
";
gets(name);
cout<<"Enter the Roll Number
: ";
cin>>Roll_No;
}
};
class test
{
protected:
float Sci;
float maths;
float english;
public:
void getMarks()
{
cout<<"\nEnter the marks of
Science :";
cin>>Sci;
cout<<"Enter the marks of
Maths :";
cin>>maths;
cout<<"Enter the marks of
English :";
cin>>english;
}};
class result : public student
, public test
{
protected:
float per;
public:
void calresult()
{
per=maths+Sci+english;
per=per/3;
}
void show()
{
cout<<"\nName :"<<name;
cout<<"\nRoll_No :"<<Roll_No;
cout<<"\nPercentage:"<<per<<"%\n";
}
};
int main()
{ result
stud;
stud.getData();
stud.getMarks();
stud.calresult();
stud.show();
}
3.
Multilevel Inheritance
Code:
#include<conio.h>
#include<iostream>
#include<stdio.h>
using namespace std;
class student
{
protected:
int Roll_No;
char name[20];
public:
void getData()
{
cout<<"Enter the Name :
";

cout<<"Enter the Roll Number
: ";
cin>>Roll_No;
}
};
class test:public student
{
protected:

float maths;
float english;
public:
void getMarks()
{
cout<<"\nEnter the marks of
Science :";
cin>>Sci;
cout<<"Enter the marks of
Maths :";
cin>>maths;
cout<<"Enter the marks of
English :";
cin>>english;
}
};
class result :public test
{
protected:
float per;
public:
void calresult()
{

per=per/3;
}
void show()
{
cout<<"\nName :"<<name;
cout<<"\nRoll_No :"<<Roll_No;
cout<<"\nPercentage:"<<per<<"%\n";
}
};
int main()
{
result stud;
stud.getData();
stud.getMarks();
stud.calresult();
stud.show();
}
4.
Hierarchical Inheritance
Code:
#include<conio.h>
#include<iostream>
#include<stdio.h>
using namespace std;
class student
{
protected:
int Roll_No;
char name[20];
public:
void getData()
{
cout<<"Enter the Name :
";
gets(name);
cout<<"Enter the Roll Number
: ";
cin>>Roll_No;
}
};
class test:public student
{
public:
float Sci;
float maths;
float english;
void getMarks()
{
cout<<"\nEnter the marks of
Science :";
cin>>Sci;
cout<<"Enter the marks of
Maths :";
cin>>maths;
cout<<"Enter the marks of
English :";
cin>>english;
}
void display()
{
cout<<"\nName :"<<name;
cout<<"\nRoll_No :"<<Roll_No;
}
};
class result : public student
{
protected:
float per;
public:
void calresult(test t1)
{
per=t1.maths+t1.Sci+t1.english;
per=per/3;
}
void show()
{
cout<<"\nPercentage:"<<per<<"%\n";
}
};
int main()
{
test t;
t.getData();
t.getMarks();
result r;
r.calresult(t);
t.display();
r.show();
}
5.
Hybrid Inheritance
Code:
#include<conio.h>
#include<iostream>
#include<stdio.h>
using namespace std;
class student
{
protected:
int Roll_No;
char name[20];
public:
void getData()
{
cout<<"Enter the Name :
";
gets(name);
cout<<"Enter the Roll Number
: ";
cin>>Roll_No;
}
};
class test:public student
{
protected:
float Sci;
float maths;
float english;
public:
void getMarks()
{
cout<<"\nEnter the marks of
Science :";
cin>>Sci;
cout<<"Enter the marks of
Maths :";
cin>>maths;
cout<<"Enter the marks of English
:";
cin>>english;
}
};
class sports
{
protected:
char grade;
public:
void getGrade()
{
cout<<"\nEnter the Grade :
";
cin>>grade;
}
};
class result :public test ,
public sports
{
protected:
float per;
public:
void calresult()
{
per=maths+Sci+english;
per=per/3;
}
void show()
{
cout<<"\nName :"<<name;
cout<<"\nRoll_No :"<<Roll_No;
cout<<"\nSports
Grade:"<<grade;
cout<<"\nPercentage :"<<per<<"%\n";
}
};
int main()
