What will be the output of the following code?

    Example()
    {

class Example {
private:
    int a;
    int b;

public:
    Example(int a, int b)
    {
        this->a = a;
        this->b = b;
    }
    int get_a()
    {
        return a;
    }
    int get_b()
    {
        return b;
    }
};

//main() code
int main()
{
    Example Ex(10, 20);
    cout << "a = " << Ex.get_a() << ", b = " << Ex.get_b();

    return 0;
}

A destructor is used to destroy the objects that have been created by a ………………..
