Can we have private constructors in c++? If yes, what is the use of it?

Answer 1

Thank you all

Answer 2

Yes

Answer 3

For creating an object of that class within the class itself

Answer 4

Sample uses (there are others):

- Several overloaded public constructors can forward-call a private constructor to implement constructor functionality after doing some type conversions.

- A public factory method can call a private constructor to control creation of this class's objects.
