My understanding is that void is used before a method that will not return a result. But it's also used in front of methods that are doing a calculation, and definitely returning a result. Where am i misunderstanding this?

#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()???
