Deconstructors can’t throw

You cant throw an exception from a deconstruction method of a class because all destroy methods are noexcept(true).

#include <iostream>


class MyClass {
public:
    MyClass() = default;
    ~MyClass() = default;
};

int main()
{
    MyClass a;
    // Deconstructions are noexept true
    std::cout << "Deconstruction status " 
              << std::boolalpha << noexcept (a.~MyClass()) 
              << std::endl;
    return EXIT_SUCCESS;
}

#include <iostream>

class MyClass {

public:

MyClass() = default;

~MyClass() = default;

};

int main()

{

MyClass a;

// Deconstructions are noexept true

std::cout << "Deconstruction status "

<< std::boolalpha << noexcept (a.~MyClass())

<< std::endl;

return EXIT_SUCCESS;

}
