Question

Explain the type of inheritance with code.

Answer 1

//1 - C++ Program to demonstrate single inheritance
#include <iostream>


using namespace std;
class ClassOne
{
    public:
        void classOneGreet()
        {
            cout<<"Hello from class One"<<endl;
        }


};
class ClassTwo : public ClassOne //One is the base class of Class two and Class Two inherits only one class.
{
    public:
        void classTwoGreet()
        {
            cout<<"Hello from class Two"<<endl;
        }
};
//Driver code
int main()
{
    ClassTwo classTwo;
    classTwo.classOneGreet();
    classTwo.classTwoGreet();
    return 0;
}

//2 - C++ Program to demonstrate multiple inheritance
#include <iostream>


using namespace std;
//Multiple inheritance
class ClassOne
{
    public:
        void classOneGreet()
        {
            cout<<"Hello from class One"<<endl;

{
    public:
        void classTwoGreet()
        {

//ClassThree inherits more than one class
class ClassThree : public ClassOne, public ClassTwo

    public:
        void classThreeGreet()
        {

//3 - C++ Program to demonstrate hierachical inheritance. This process derives more than one class from a base class.
#include <iostream>
