C++ Inheritance: Calling Base Class Constructor In Header

Question

Assume class Child is a derived class of the class Parent. In a five file program, how would I specify in Child.h that I want to call

Answer 1

The initialization list of a constructor is part of its definition. You can either define it inline in your class declaration

class Child : public Parent {
    // ...
    Child(int Param, int ParamTwo) : Parent(Param)
    { /* Note the body */ }
};

or just declare it

class Child : public Parent {
    // ...
    Child(int Param, int ParamTwo);
};

and define in the compilation unit (Child.cpp)

Child::Child(int Param, int ParamTwo) : Parent(Param) {
}
