C++ Program using Virtual Base Class to to find the prime numbers within a range of numbers

Write a program in C++ to find the prime numbers within a range of numbers by using the Virtual base Class in Object Oriented Programming(OOP).

#include<iostream>
using namespace std;
class A
{
	protected:
		int i,n;
};
class B:virtual public A
{
	protected:
		int T4Tutorials_StartingNum,T4Tutorials_EndigNum;
};
class C:virtual public A
{
	protected:
		int c;
};
class D:public B,public C
{
	public:
		int prime()
		{
				cout<<"enter starting no rnge"<<endl;
	cin>>T4Tutorials_StartingNum;
	cout<<"enter ending no rnge"<<endl;
	cin>>T4Tutorials_EndigNum;
	cout<<"the prime numbers btw"<<T4Tutorials_StartingNum<<" "<<T4Tutorials_EndigNum<<" ";
    for(n=T4Tutorials_StartingNum;n<=T4Tutorials_EndigNum;n++)
	{
		c=0;
		for(i=2;i<=n/2;i++)
		{
			if(n%i==0)
			{
				c++;
				break;
			}
		}
		if(c==0&&n!=1)
		cout<<n<<" ";
		 }	 
		 cout<<endl;
}
};
int main()
{
	D obj;
	obj.prime();
}
