No Matching Function Call to Base class

Question

Here I am trying to make a subclass of the base class, Airplane. In my main code I haven\'t tried to use either constructor yet as I am just trying to make sure I can make t

Answer 1

When this constructor is called

Fighter::Fighter(int engines, int seats, string desc)
{
    fNumEngines = engines;
    fNumSeats = seats;
    rangeSpeed = desc;
}

then it calls the default base class constructor. However class Airplane does not have the default constructor. It has a constructor with parameters

Airplane(int, int);

So you need explicitly calll the constructor in the mem-initializer list of the constructor Fighter

For example

Fighter::Fighter(int engines, int seats, string desc) : Airplane( engines, seats )
{
    fNumEngines = engines;
    fNumSeats = seats;
    rangeSpeed = desc;
}

Also it is not clear why the data members of the base class and the derived class are duplicated.
