Code runs but printing error.

[Blackhart98]

Ok so I made this textdialougeTree. It suppose to print out the dialouge ,and choices. But I am getting nothing just press any key to continue. How come that is happening? Here is the code please help me find out what is going wrong. Please don't ask me what is exactly the problem if I knew i wouldn't be asking this question. It just prints nothing at all it runs with no errors whatsoever it just doesn't print anything.
main.cpp

  #include <iostream>
#include <string>

    Mana = 100;

      virtual void TheenemyHealth(){}
     virtual int EnemyDamage(int EnemyAttack){
int  Attack = EnemyAttack;
     Attack = 15;
     return Attack;
    }

    int Strenght = 0;


};

    Attack = 5;
    }

AGAIN...Please don't ask "What is your question exactly". My question is to help find out whats wrong with my code. Its printing nothing from my DialougeTree nothing at all. Just printing "press any key to continue..."

One method of debugging is to add more "print" commands to various places to find out which paths does the execution follow.
