How dependent is a baby chicken on parent?
chickens don't need their parents they learn them self's.
What do you mean by forward declarations of a class in c plus plus?
Which came first, the chicken or the egg? The answer is, of course, the egg. After all, birds evolved long after egg-laying reptiles, so eggs had to have come first. But what exactly does that have to do with forward declarations? Well, everything, as it turns out. Forward declarations are essential whenever two classes depend on each other.As you know, in C++ you must define a type before you can use it. So let's define a simple chicken and egg:#include class Chicken{public:Chicken(Chicken* parent=0):m_pParent(parent){}Egg* lay_egg();private:Chicken* m_pParent;};class Egg{public:Egg(Chicken* parent=0): m_pParent(parent){}Chicken* hatch();private:Chicken* m_pParent;};Egg* Chicken::lay_egg(){return(new Egg(this));}Chicken* Egg::hatch(){return(new Chicken(m_pParent));}int main(){Chicken chicken;Egg* egg = chicken.lay_egg();Chicken* chick = egg->hatch();Egg* egg2 = chick->lay_egg();delete(egg2);egg2=0;delete(chick);chick=0;delete(egg);egg=0;return(0);}Straight away there's a problem. The compiler won't allow this because our chicken lays eggs but the definition of an egg appears after the definition of a chicken. Ah, but of course -- eggs came first! So let's swap the definitions around:#include class Egg{public:Egg(Chicken* parent=0): m_pParent(parent){}Chicken* hatch();private:Chicken* m_pParent;};class Chicken{public:Chicken(Chicken* parent=0):m_pParent(parent){}Egg* lay_egg();private:Chicken* m_pParent;};Egg* Chicken::lay_egg(){return(new Egg(this));}Chicken* Egg::hatch(){return(new Chicken(m_pParent));}int main(){Chicken chicken;Egg* egg = chicken.lay_egg();Chicken* chick = egg->hatch();Egg* egg2 = chick->lay_egg();delete(egg2);egg2=0;delete(chick);chick=0;delete(egg);egg=0;return(0);}Hmm. The compiler's still not happy. Our eggs need to hatch chickens but, again, the definition of a chicken now appears after the definition of an egg. We seem to have a catch-22 situation. No matter which order we define them, we simply cannot emulate a simple chicken and an egg.The answer is, you guessed it, to use a forward declaration:#include class Chicken; // forward declaration!class Egg{public:Egg(Chicken* parent=0): m_pParent(parent){}Chicken* hatch();private:Chicken* m_pParent;};class Chicken{public:Chicken(Chicken* parent=0):m_pParent(parent){}Egg* lay_egg();private:Chicken* m_pParent;};Egg* Chicken::lay_egg(){return(new Egg(this));}Chicken* Egg::hatch(){return(new Chicken(m_pParent));}int main(){Chicken chicken;Egg* egg = chicken.lay_egg();Chicken* chick = egg->hatch();Egg* egg2 = chick->lay_egg();delete(egg2);egg2=0;delete(chick);chick=0;delete(egg);egg=0;return(0);}Now the code compiles!The forward declaration simply acts as a sort of place-holder. We're just telling the compiler that although we aren't quite ready to define a chicken, one will be defined at some point -- it may even be in a completely different file. But that is enough to appease the compiler, it can simply fill in the blanks when our chicken is fully defined.This type of scenario crops up quite a lot, especially when working with parent and child classes that must depend on each other, just like our chicken and egg. However, we normally design our classes using separate source files each with their own header file, and that would then make it impossible for our chicken and egg header's to include each other's header. Instead, we must use forward declarations in the headers, and place the corresponding #include directives in the source files.
If the chicken came first what made that egg?
Something that was nearly a chicken. The way natural selection works, is through gradual change due to mutations in reproduction, so the parent of the first chicken eggs wasn't a chicken, but a bird that was almost a chicken that laid mutated eggs.
What if a parent has shingles and child has not been vaccinated for chicken pox?
Go get the vaccine for the child. The shingles is because you had chicken pox at some point, but I don’t think that there would be a direct transmission.
What are the characteristics of a guinea and chicken crossbreed?
A crossbreed between a guinea and a chicken, known as a guin-hen, typically exhibits a mix of traits from both parent species. These hybrids may have a unique appearance, combining features such as the guinea's slender body and chicken's feathers. They may also display a blend of behaviors, such as the guinea's alertness and the chicken's social nature. Overall, guin-hens can vary in their characteristics, depending on the specific traits inherited from each parent.
What comes out first chicken or chick?
It depends entirely on what you believe to be a chicken and a chick. Of course, every organism is different and we are constantly evolving so we are all distinct due to the fact that our/every creature's DNA is an infusion of its parent's DNA.
Why would a parent expose a child to another child that has chickenpox?
Because the earlier they get chicken pox, the better. The older you get you can get complications and they are a lot worse. Once you have chicken pox as a child your body is then immune so it's unlikely you will have them as an adult.
Which company is the largest buyer of chicken?
Yum! Brands, the parent company of fast-food chains like KFC, Taco Bell, and Pizza Hut, is one of the largest buyers of chicken in the world. They use chicken as a primary ingredient in many of their menu offerings across their various restaurant chains.
Did the chicken come befor the egg?
My belief is that the egg came before the chicken. There was a bird ancestor to the modern chicken. Mutations (genetic changes) occur and the new characteristics show up in the chick in the egg. So the new, modern breeds are due to changes which show up in the egg, not in the parent bird.
Who is the parent company of Kentucky Fried Chicken?
Formerly owned by Pepsi Cola it is currently held by Yum! Brands.
