C++ Program using Virtual Base Class to to o check whether a number is a Strong

Write a C program to check whether a number is a Strong Number or not using the Virtual base Class in Object Oriented Programming(OOP).

#include<iostream>
using namespace std;
class Grand_FatherT4Tutorials
{
	public :
		int ip;
};
class p1:virtual public Grand_FatherT4Tutorials
{
	public :
		int sum;
};
class p2:virtual public Grand_FatherT4Tutorials
{
	public :
		int save;
};
class derived:public p1,public p2
{
	protected :
		int fact,num;
	public :
		s_num();
};
derived::s_num()
		{
			sum=0;
			cout<<"Enter number to check: ";
			cin>>ip;
			save=ip;
			while(ip)
			{
				num=ip%10;
				fact = 1;
				for(int i=num;i>0;i--)
				{
					fact=fact*i;
				}
				sum+=fact;
				ip/=10;
			}
			if(sum==save)
			{
				cout<<save<<" is a Strong Number";
			}
			else
			{
				cout<<save<<" is not a Strong Number";
			}	
		}
int main()
{
	derived a;
	a.s_num();
	
}
