How to write this program-:
since it is multiple inheritance, so make 2 base classes and 1 derived class.
we need to show the constructor and destructor invocation, so create constructors and destructors and enter some information within them.
eg-: cout<<“this is base class constructor”;
From the int main function, use the method of calling constructors

[read from here]
or just create a derived class object and done.

#include<iostream> using namespace std; class Base1 { public: Base1() { cout<<"Base1 class constructor"; cout<<endl; } ~Base1() { cout<<"Base1 class destructor"; cout<<endl; } }; class Base2 { public: Base2() { cout<<"Base2 class constructor"; cout<<endl; } ~Base2() { cout<<"Base2 class destructor"; cout<<endl; } }; class derived:public Base1,public Base2 { public: derived() { cout<<"derived class constructor"; cout<<endl; } ~derived() { cout<<"derived class destructor"; cout<<endl; } }; int main() { { derived d; } return 0; } |
Output-:
Base1 class constructor
Base2 class constructor
derived class constructor
derived class destructor
Base2 class destructor
Base1 class destructor
