About Polymorphism in C++

I'm learning about polymorphism and this is a small game. I have a representative class Character here, I want to program so that from a Character people can choose Warrior or Archer to continue the game.

#pragma once
#include <iostream>
using namespace std;
#include <string>

class Warrior;
class Archer;

class Character {
   public:
   Character(void);
   ~Character(void);

Character* creatCharacter(int choice, string CharacterName) {

    if (choice == 1)
        return (Character*)new Warrior(CharacterName);

    if (choice == 2)
        return (Character*)new Archer(CharacterName);

      return NULL;
   }

   virtual void Skill_Cast() {};
};

class Warrior :public Character {
private:
   string name;
public:
   Warrior(void);
   ~Warrior(void);

   Warrior(string CharacterName) {
      name = CharacterName;
   }


  void Skill_Cast() {
      cout << "Punch!" << endl;
  }

 };

class Archer : public Character
{ 
private:
    string name;
public:
Archer(void);
~Archer(void);

Archer(string CharacterName) {
    name = CharacterName;
}

   void Skill_Cast() {
    cout << "Shoot!" << endl;
   }

};

In the main function:

int main() {
   cout <<"Enter character's name: ";
   string name;
   getline(cin, ten, '\n');
   cout <<"Enter your character class by number (1),(2),(3): ";
   int choice;
   cin >> choice;

   Character* YourChar;



  YourChar = YourChar->creatCharacter(choice, name);

  YourChar->Skill_Cast();
}

And this is ERRORS:

 Error  1   error C2512: 'Warrior' : class has no constructors  
 Error  2   error C2514: 'Archer' : class has no constructors   

Can you explain me the errors and help me fix that, by the way, Is this a kind of "Abstract Factory Design Pattern" ? Thanks so much. (sorry for my bad English)
