[ACCEPTED]-Can functions accept abstract base classes as arguments?-abstract-class
Accepted answer
You cannot pass an Animal object to the derived 8 class function because you cannot create 7 an object of Animal class et all, it is an Abstract class.
If 6 an class contains atleast one pure virtual 5 function(speak()) then the class becomes an Abstract 4 class and you cannot create any objects 3 of it. However, You can create pointers 2 or references and pass them to it.
You can 1 pass an Animal pointer or reference to the method.
void speakTo(Animal* animal)
{
animal->speak();
}
int main()
{
Animal *ptr = new Dog();
speakTo(ptr);
delete ptr; //Don't Forget to do this whenever you use new()
return 0;
}
You will need to pass a reference instead 1 of a copy:
void speakTo(Animal& animal) {
animal.speak();
}
