c++ class error

[ssm]

i made a simple Animal class but when i try to build and run the class it give me many error i can't understand where i made mistake

#include <iostream>


using namespace std;


class Animal{
    
public:
    //class public members
    int GetAnimalAge();
    int GetAnimalWeight();
    
    void SetAnimalAge(int age);
    void SetAnimalWeight(int weight);
    
    void AnimalSound();
    
    
private: 
    // class private members
    int animalAge;
    int animalWeight;
};


void Animal::GetAnimalAge(){
    return animalAge;
}


void Animal::GetAnimalWeight(){
    return animalWeight;
}


int Animal::SetAnimalAge(int age){
    animalAge = age;
}


int Animal::SetAnimalWeight(int weight){
    animalWeight = weight;
}






void AnimalSound(){
    cout << "dog barks " << endl;
}




int main(int argc, char **argv)
{
	cout << "c++ classes " << endl;
    
    // creating class object
    
    Animal Dog;
    
    Dog.SetAnimalAge(2);
    Dog.SetAnimalWeight(8);
    
    cout << "dog age is " << Dog.GetAnimalAge() << " years " << endl;
    cout << "dog weight is " << Dog.GetAnimalWeight() << " kg" << endl;
    Dog.AnimalSound();
    
	return 0;
}

Just got mixed up with the return types, eh?

This is running code [You used different return types while defining functions]

#include <iostream>
 
 using namespace std;


class Animal
{
public:
    //class public members
    int GetAnimalAge();
    int GetAnimalWeight();
     
    void SetAnimalAge(int age);
    void SetAnimalWeight(int weight);
     
    void AnimalSound();
    
private: 
    // class private members
    int animalAge;
    int animalWeight;
};
 
 
int Animal::GetAnimalAge(){
    return animalAge;
}
 
 
int Animal::GetAnimalWeight(){
    return animalWeight;
}
 
 
void Animal::SetAnimalAge(int age){
    animalAge = age;
}
 
 
void Animal::SetAnimalWeight(int weight){
    animalWeight = weight;
}
 
void Animal::AnimalSound(){
    cout << "dog barks " << endl;
}
 
 
 
 
int main(int argc, char **argv)
{
    cout << "c++ classes " << endl;
     
    // creating class object
     
    Animal Dog;
     
    Dog.SetAnimalAge(2);
    Dog.SetAnimalWeight(8);
     
    cout << "dog age is " << Dog.GetAnimalAge() << " years " << endl;
    cout << "dog weight is " << Dog.GetAnimalWeight() << " kg" << endl;
    Dog.AnimalSound();
     
    return 0;
}
