What happens when you attempt to compile and run the following code?

#include

#include

class A {

public:

virtual int f() { return 10; }

virtual ~A(){}

};

class B: public A {

int f() {return 11; }

virtual ~B(){}

};

int main (){

std::vectorv1;

for(int i = 10; i>0; i??)

{

i%2>0?v1.push_back(new A()):v1.push_back(new B());

}

std::vector::iterator it = v1.begin();

while(it != v1.end())

{

std::cout<<v1.back()?>f()<<" ";

v1.pop_back();++it;

}

return 0;
