Polymorphism in C++

Question

AFAIK:

C++ provides three different types of polymorphism.

• Virtual functions
• Function name overloading
• Operator overloading

Answer 1

Here is a basic example using Polymorphic classes

#include 

class Animal{
public:
   Animal(const char* Name) : name_(Name){/* Add any method you would like to perform here*/
    virtual void Speak(){
        std::cout << "I am an animal called " << name_ << std::endl;
    }
    const char* name_;
};

class Dog : public Animal{
public:
    Dog(const char* Name) : Animal(Name) {/*...*/}
    void Speak(){
        std::cout << "I am a dog called " << name_ << std::endl;
    }
};

int main(void){
    Animal Bob("Bob");
    Dog Steve("Steve");
    Bob.Speak();
    Steve.Speak();
    //return (0);
}
