faq the c++ will not provide the default constructor?

Hi,
If we do not provide the default constructor(non-parameter constructor),
the compiler will create one for us.
If we have a constructor with parameter and we do not provide the
non-parameter constructor, wether the compiler create default constructor
for us?
Thank you very much.

If a constructor has parameters, all the parameters have default
values. The constructor aslo is default. Otherwise, you need to provide
no-parameter constructor as default.

Thank you dan2online.
If a constructor has parameters, all the parameters have default values. Is it I must provide the default values?
The constructor aslo is default.

Is it be take as the "only one" default ctor(The word I learned just hours
ago)?

Thank you.

Hi, I am writing a program and needs to know one of its object members before it can be initialized. It doesn't really matter for my question (which a C++ question, not a windows question), but the class is used in a windows program and has an HWND member ( a handle to a window), and to make an sense the class must know what the member is. But this puts me in the position of having no default constructor, and I've heard that is...

If I don't define a default constructor for my class "Foo", I still get one from the compiler. But if I define a constructor that takes an argument, I don't get the default constructor, why? I understand that this is a rule in the language, but what is the motivation of this rule?

Hello, I understand the default-initialization happens if we don't initialize an object explicitly. I think for an object of a class type, the value is determined by the constructor, and for the built-in types, the value is usually garbage. Is this right? However, I'm a bit confused about value-initialization, when does it happen, and what kind of values are assigned to objects?

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
