How does a constructor in a base class get called when an object of a derived class is created?

When an object of a derived class is created, the constructor of the base class gets called automatically. This happens because inheritance allows properties and methods to be passed from one class to another. The process begins with the creation of the derived class object. During this instantiation, the derived class’s constructor is invoked first. However, before executing its own body, it implicitly calls the base class’s constructor. If there are multiple levels of inheritance, this chain continues upwards until reaching the topmost base class. It’s important to note that if the base class has parameterized constructors only, the derived class must explicitly call them using the ‘super’ keyword in Java or the base keyword in C#.
