Infamous Vtable error (in my books)

Blackhart98 (97)
I am now getting a vtable error for my enemy class in my rpg game. It says undefined refernce to 'Vtable for Enemy' . I'm thinking its my constructor that is going wrong with the Enemy class. I've tried almost everything but kept getting stumped on a problem. Here is my enemy.cpp class

#include <iostream>
Monster::Monster(int MonsterHealth,int MonsterMana,int Monstersize,int Monsterenemymana) // implementation
 : Health(MonsterHealth), Mana(MonsterMana), Enemy(Monstersize,Monsterenemymana) {}


int Monster::dropxp(int enemydropxp){


}

So the probelem lies within the constructors ,but I don't know which one and why. I don't mind you changing up my entire code I love improvements towards everything I do.

You did not define all declared functions.

You're not defining Enemy::dropxp(int enemydropxp); :)
also you may want to look up abstract classes! It'll probably fit your situation a little better but you be the judge.
