Can someone explain this code to me....
class ReverseNumberDemo
{ public static void main(String args[]) {
int num=123456789;
int reversenum =0;
while( num != 0 ) {
reversenum = reversenum * 10;
reversenum = reversenum + num%10;
num = num/10; }
System.out.println("Reverse of specified number is: "+reversenum);
}
}
the thing I don't get is the reversenum part......isn't reversenum=0 so wouldn't reversenum*10=0

#include <iostream>
using namespace std;
class A{
public:
void f1();
};
class B : public A{
public:
virtual void f1();
}
int main()
{
A * obj = new B;
obj.f1();
}
Ques: can we write virtual before an overridden function from the base class?? if yes which f1() should it call base class f1() or derived class f1()???
