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

#include

#include

using namespace std;

class A

{

int a,b;

public:

A & operator =(const A & c) { a = c.a; return *this;}

A():a(0),b(0){}

void setA(int a) {this?>a = a;} void setB(int b) {this?>b = b;}

int getA() {return a;} int getB() {return b;}

};

int main ()

{

vectorv;

A a;

a.setA(10); a.setB(11);

v.push_back(a);

A b = v.front(); v.pop_back();

cout<

return 0;

}
