Question #105 Difficulty: 2

According to the C++17 standard, what is the output of this program?

    #include <iostream>

using namespace std;

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

int i = 1;

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

Hint:

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?
