Base Class and Derived Class Constructor Arguments

Question

Peace be upon those who follow the guidance,

Let’s suppose I have a base class that has a constructor which takes parameters. So instantiating an object from this class requires passing arguments. Suppose I have a derived class which inherits from the base class, and this derived class also takes parameters in its constructor. So, how do I pass arguments to both constructors? Please forgive me if this is a trivial question.

Answer 1

Just call the base constructor inside the derived constructor's initializer list like:

Derived( int param1, double param2 )
: Base( param1, param2 )
{}
