    {
    if(element%i==0)
    {
    sum+=i;
    }
    }
    }

int chksum()
{

cout<<"Yes!!"<<endl<<"the element is perfect number"<<endl<<endl;
else
cout<<"Not!!"<<endl<<"the element is not a perfect number"<<endl;
}
};


int main()

chknelement per;
int value;
cout<<"the element to check perfect or not : ";
cin>>value;
per.setelement(value);
per.getperfect();
per.chksum();
return 0;
}
