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;}};
