The document discusses different types of inheritance in C++ including single, multilevel, multiple, hierarchical, and hybrid inheritance. Examples are provided for each type of inheritance using C++ class definitions and code snippets. Single inheritance allows a derived class to inherit from one base class. Multilevel inheritance allows a derived class to inherit from another derived class. Multiple inheritance allows a class to inherit from more than one base class. Hierarchical inheritance involves a main base class with multiple derived classes. Hybrid inheritance combines more than one type of inheritance.

3. Types of Inheritance:
Single Inheritance.
Multilevel Inheritance
Multiple Inheritance.
Hierarchical Inheritance.
Hybrid Inheritance.

4. Single Inheritance:
Example:
#include<iostream>
using namespace std;
class dox
{
int a;
public:
int b,c;
dox();
~dox();
};

5. class box : public dox
{
public:
int x,y;
box();
void multi();
void add();
~box();
};
dox :: dox()
{ cout<<"enter a number:"<<endl;
cin>>a; }
dox::~dox()
{cout<<"number:"<<a<<endl; }
box :: box()
{ cout<<"enter two
number:"<<endl; cin>>b>>c; }
void box :: multi()
{ x=b*c; }
void box :: add()
{ y=b+c; }
box :: ~box()
{cout<<"multiply:"<<x<<endl;
cout<<"addition:"<<y<<endl; }
int main()
{ box j;
j.multi();
j.add();
return 0;
}

6. Multilevel Inheritance:
Example:
#include<iostream>
using namespace std;
class a
{
protected:
int d,i=20,j=2;
public:
void devided()
{
d=i/j;
}
};

7. class b : public a
{
protected: int x=33,y=2,z;
public:
void reminder()
{
devided();
z=x%y;
}
};
class c : public b
{
public:
void display()
{
cout<<"divided:"<<d<<endl;
cout<<"reminder:"<<z<<endl;
}
};
int main()
{
c n;
n.reminder();
n.display();
}

8. Multiple Inheritance:
Example:
#include<iostream>
using namespace std;
class x
{
protected :
int a;
public:
void get_age(){
cout<<"enter
age:"<<endl;
cin>>a;
}};

9. class y
{
protected :
int id;
public:
void get_id()
{ cout<<"enter Id:"<<endl;
cin>>id;
}};
class z :public x,public y
{
public:
void out()
{
cout<<"nid:"<<id<<"nage
"<<a<<endl; }};
int main()
{
z i;
i.get_age();
i.get_id();
i.out();
Return 0;
}

10. Hierarchical Inheritance:
Example:
#include<iostream>
using namespace std;
class A
{ public:
int a;
void getnumber()
{cout<<"nEnter
Number :";
cin>>a;
}};

11. class B : public A
{
public:
void square()
{getnumber();
cout<<"Square of the
number :"<<(a*a);
}};
class C :public A
{public:
void cube()
{getnumber();
cout<<"nCube of the
number :"<<(a*a*a);
}};
int main()
{
B b1;
b1.square();
C c1;
c1.cube();
}

12. Hybrid Inheritance:
Example:
#include<iostream>
using namespace std;
class A
{protected:
int s;
public:
void get_value()
{
cout<<"enter speaking
score:"<<endl;
cin>>s;}};

13. class B:public A
{
protected : int r;
public:
void in(){
cout<<"enter reading
score:"<<endl;
cin>>r;
}};
class C
{
protected: int w,l;
public:
Void put_value()
{cout<<"enter writing
score:"<<endl;
cin>>w;
cout<<"enter listening
score:"<<endl;
cin>>l;}};
class V:public C,public B
{
int avg,add;
public:
void out()
{
add=s+w+l+r;
avg=(s+w+l+r)/3;
cout<<"addition of the
scores:"<<add<<endl;
cout<<"average of the
scores:"<<avg<<endl;}};

14. int main()
{
V i;
i.get_value();
i.in();
i.put_value();
i.out();
return 0;
}
