For given class:

class C
{
    // ...
}

What's the difference between

class C
{
    // ...
    C() { };
    ~C() { };
    // ...
}

and

class C
{
    // ...
    C() = default;
    ~C() = default;
    // ...
}

Are they doing the same?

Are you sure that you want ctor/dtor to be private? – Karlis Olte Jul 06 '15 at 09:35

Possibly also interesting in this context: `C(/* ... */) = delete;`, which explicitly forbids the compiler to generate a default constructor. – nils Jul 06 '15 at 09:47
@KarlisOlte of course, I mean public, the question is not about visibility – vladon Jul 06 '15 at 11:12
