Buckys C++ Programming Tutorials – 55 – Introduction to Polymorphism

I am a ninja, ninja chop!

I still don't understand that. Is there posible to not using pointers? Do i must use pointer in this example?

it's basically object typecasting. the ninja object should be equal to or bigger than the enemy object. try Enemy* enemy1 = (class Enemy*)&n; and see if that produces the same result.

why he used the pointer way to insert the info in the function ??
why he didn't use the normal way
like this
int main() {

ninja n;

monster m;

n.setattackpower(29);

m.setattackpower(99);

n.attack();

m.attack();

};

???

I tried the same question with out pointer variable and used dot operator and i am getting some garbage values as attack power can some one please tell me why?????????

Sir Bucky, these are nodoubt The Best! c++ tutorials. Love you 💕

Bucky is a great programming instructor. You can use enemy1 and enemy2 if they were Ninga and monster type respectively. Also you can access the function by pointer (if it was a Ninga type for example) by typing enemy1->attack();

Why use pointer? Is there any advantage of using pointer?

you called n.attack( ) and m.attack( ). This doesn't show that the code knew which attack to call. Cz you're literally telling the code which attack to call. You should've called attack to the e1 like e1->attack( ). That would show the intelligence of the code to know which attack to call. But for that you need to make a virtual attack( ) in enemy.

Thank you sooooo much bro. These examples are exactly what i need! you da best

thank you sir

good explaination!

Why there was pointers in the code? was it really needed?

Nice Tutorial !

Says you should never copy.
Keeps copying throughout the whole tutorial series.
