  • What are the rules for calling the base class constructor?
    1190 Base class constructors are automatically called for you if they have no argument If you want to call a superclass constructor with an argument, you must use the subclass's constructor initialization list Unlike Java, C++ supports multiple inheritance (for better or worse), so the base class must be referred to by name, rather than
  • Can I call a constructor from another constructor (do constructor . . .
    When calling a constructor it actually allocates memory, either from the stack or from the heap So calling a constructor in another constructor creates a local copy
  • Whats the difference between an object initializer and a constructor?

  • Can an abstract class have a constructor? - Stack Overflow

  • c++ - no default constructor exists for class - Stack Overflow
    80 If you define a class without any constructor, the compiler will synthesize a constructor for you (and that will be a default constructor -- i e , one that doesn't require any arguments)
  • c++ - Initializing fields in constructor - initializer list vs . . .
    6 In your example code, the first one in constructor initialization and second one is assignment inside constructor body Constructor initialization list is the best way to do all member initialization because it improves performance
