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

#include

#include

using namespace std;

class A {

int a;

public:

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

int getA() const { return a; } void setA(int a) { this?>a = a; }

bool operator==(A & b) { return a == b.a; }

};

struct Compare{

bool operator()(const A & a, const A & b) {return a.getA()==b.getA();};

};

int main () {

int t[] = {1,2,3,4,5,1,2,3,4,5};

vector v (t,t+10);

vector::iterator it;

A m1[] = {A(1), A(2), A(3)};

it = find_end (v.begin(), v.end(), m1, m1+3, Compare());

cout << "Found at position: " << it?v.begin() << endl;

return 0;
