How to mock static method call by constructor?

Can you call public methods from a constructor in C++?

• Can I call public function in constructor to initialize the private member variables? I Googled and found one should not use virtual functions and public functions in constructor, whereas we can always use private member functions in constructor.

• Answer:

  There is no prohibition against calling public methods from a constructor in C++. Nothing wrong with it at all. There is also nothing wrong with public methods initializing private variables, or vice versa. Whether a method is public, private, or protected is irrelevant—those are just access restrictions. There are two things of which a constructor need be mindful: Calling virtual methods and calling functions that manipulate member variables that are initialized later in the constructor. The latter isn't a rule, just common sense, but is an easy mistake to make.
