Question #105 Difficulty:

According to the C++11 standard, what is the output of this program?

#include <iostream>

using namespace std;

class A {
  A() { cout << "a"; }
  ~A() { cout << "A"; }

int i = 1;

int main() {
  A a;
  if (i--)
    goto label;


Control passes through A a; twice. Does it make more sense to construct a both times, or just the first? Should the destructor be called the same number of times as the constructor?

I give up, show me the answer (make 3 more attempts first).
