Question #105 Difficulty:
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?
Problems? View a hint or try another question.
I give up, show me the answer (make 3 more attempts first).
