What is the role of constructors in C++ inheritance?

In C++ inheritance, constructors initialize base class members before derived class members. This ensures proper setup.

Can you explain how to call a base class constructor from a derived class?

Sure! You can call a base class constructor in the derived class's constructor initializer list using the syntax: BaseClassName(args). For example: DerivedClass(args) : BaseClassName(args) {}.

What happens if I don't call the base class constructor?

If you don't explicitly call the base class constructor, the default constructor of the base class will be called automatically, if it exists. If the base class has no default constructor, it will result in a compilation error.

Are there any special rules for constructors in multiple inheritance?

Yes, in multiple inheritance, constructors of all base classes are called in the order they are listed in the derived class's constructor initializer list. This ensures that all base class members are properly initialized.
