Code Crash Issue

[denver2020]

My below code crashes at the below highlighted line. How can I fix it?

class Animal
{
   int age;
   float height;

public:
   virtual float Eating();
   virtual void Sleeping();
};

Animal* animal = new Animal();
//This line crashed --v
animal->Eating();

//However I am able to view the instance in watch window as:
//But not able to identify error here.
-> vftbl
   ->0x00000000
   ->Animal::Sleeping (0x04b310a0)

Do you mind showing the code for Animal::Eating?

You also need a virtual destructor on class Animal, but it doesn't make a different in this case.

Also Class Animal, should be class Animal.

It was a type error, have corrected it as class Animal. Do you mean there should be a virtual destructor here? I am not able to figure out what caused the error here.

Post real code showing the problem.

// Example program
#include <iostream>
#include <string>

class Animal
{
   int age;
   float height;

public:
   virtual float Eating();
   virtual void Sleeping();
};

float Animal::Eating() {
    std::cout << "munch\n";
    return 0.0;
}
void Animal::Sleeping() {
    std::cout << "zzzzz\n";
}

int main()
{
  Animal* animal = new Animal();
  animal->Eating();
}
