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;

}

Which changes introduced independently will allow the code to compile and display 0 0 1 1 8 8 9 9 (choose all that apply)?

#include

#include

#include

using namespace std;

class A {

int a;

public:

A(int a):a(a){}

int getA() const { return a;}

/* Insert Code Here 1 */

};

/* Insert Code Here 2*/

int main(){

A t[] ={ 3, 4, 2, 1, 6, 5, 7, 9, 8, 0 };

sets(t, t+10);/* Replace Code Here 3 */

multiset s1(s.begin(),s.end());/* Replace Code Here 4 */

s1.insert(s.begin(),s.end());

s1.erase(s1.lower_bound(2),s1.upper_bound(7));

multiset::iterator i=s1.begin();/* Replace Code Here 5 */

for( ;i!= s1.end(); i++)

{

cout<<i?>getA()<<" ";

}

cout<<endl;

return 0;

}
