Answer 1

#include<iostream>
using namespace std;
class base


{


int x;


public:
base(){
}
base (int a){
x=a;


}


void display ( )


{ 
cout <<x<<"\n";


}


};






class derived :public base


{ int d;


public:


derived (int a, int b): base (a)


{ 


d=b; 


}


void display ( )


{


cout <<d;




}


};






int main ( )


{ 


base b(5);
b.display();


derived D(10,20);
D.display();


return 0;


}
