Aim: Write a program to demonstrate dynamic constructor.

Ans:

#include<iostream.h>

#include<conio.h>

class  A

{

int n,i,*p;

public:

            A()

            {

                        clrscr();

                        cout<<"Enter the number of elements:\n";

                        cin>>n;

                        cout<<"Enter "<<n<<" values\n";

                        p=new int [n];

                        for(i=0;i<n-1;i++)

                                    cin>>p[i];

                        cin>>p[i];

                        for(i=0;i<n;i++)

                                    cout<<" "<<p[i];

            }

}o;

void  main()

{

getch();

}
