warning: definition of implicit copy constructor even though I didn't call copy constructor

Asked 2022-Jan-16 at 18:04

I am trying to run this example in https://en.cppreference.com/w/cpp/language/copy_assignment, but when I delete the default constructor and default copy constructor: A() = default; A(A const&) = default;, clang++ says that warning: definition of implicit copy constructor for 'A' is deprecated because it has a user-provided copy assignment operator [-Wdeprecated-copy-with-user-provided-copy].

My question is that I have called copy assignment instead of copy constructor, why clang++ reports copy constructor warning?

Here is my code:

This invokes A's copy constructor since other is a value copy.

Your base declaration does not match your specialization.

The base implementation has template while the specialzation wants template .

You also put an extra int that does not belong there in the declaration for the specialization here:

ANSWER

Answered 2021-Apr-19 at 14:21

In C, any argument narrower than an int is automatically promoted to an int when passed to printf, or generally when passed to any function for an argument corresponding to ... in the declaration or to any function without parameter prototypes (declared with ()). C++ Insights is explicitly showing you this promotion.

Although the %c conversion specifier prints a character, it expects to receive that character in an int argument.

The reason for the promotion is largely historical; C was developed in environments where computing in the native register size was easy and implementing specific semantics for other types required more work. So, in most expressions, integers narrower than int are promoted to int.

Cppinsight is not an implementation of the standard, and it doesn't magically generate all the code that a compiler would. The class that it shows for the lambda expression is such that the compiler will generate a copy constructor. Nevertheless, it gives you a hint:

ANSWER

Answered 2020-Oct-28 at 08:46

Your code does result in infinite recursion, you can use integral_constant::type::type::type as many times as you like.

This isn't a problem though as the compiler only instantiates templates that you are using not all the templates that you could possibly use.

You would have an error if you tried to declare a member recursively:
