In C you can invoke the base class constructor by using the base keyword in the derived class constructor declaration. Although with interfaces multiple inheritance is supported by C. In C you can pass parameters to the constructor.
A subclass must declare its own constructors. In the following example a class named Taxi is. As long as you inherit from a class this class need to have an accessible constructor.
But you have put only a private one so your Derived class wont be able to. It in his turn passes the argument to the parent class constructor with a parameter which initializes the name field. Inheritance enables you to create new classes that reuse extend and modify the behavior defined in other classes.
Whenever a class or struct is created its constructor is called. This is because C does not support multiple inheritance with classes. That being sad it has nothing to do with upfront.
C Inheritance Constructor is very useful when you need to pass value to base class from child class. The class whose members are inherited is called the base. In the next chapter you will learn Multiple Inheritance in C.
Their signature does not need to be repeated in the derived class. If you want to initialize BaseString with default value then pass that value to base class constructor thus you dont have to pass that parameter to derived class constructor. Invisible base class constructors are a result of choices made by designers of C language and quite possibly other CLR languages.
If the base class does not want them available they will be marked private.
