for 루프 외부에서 값을 반환했습니다.

Question

안녕하세요 저는 목록에서 무기를 가져 와서 플레이어 클래스에서 해당 무기를 사용하려고합니다. 내가 할 수 있다고 생각하는 방법은 모든 무기를 목록에 넣는 것입니다. 그러면 언제든지 무기 검색을 사용하여 검색에서 반환 된 값으로 무기 이름을 설정하고 싶습니다. 그러나 for 루프 외부에있는 목록 내부의 값을 반환하려고하기 때문에 런타임 오류가 발생합니다.

무기 클래스

DoublyLinkedList<Weapons> weaponsList; 
DoublyLinkedListIterator<Weapons> itr = weaponsList.getIterator(); 

    Weapons :: Weapons() 
    {

루프 바깥에 이름을 바보로 고정했습니다.

string Weapons :: searchByWeaponID(int searchByID) 
{ 
    //Loop through the Iterator. 
    for (itr.Start(); itr.Valid(); itr.Forth()) 
     { 
      //If the object entered has the same first name as the one in the loop. 
      if (itr.Item().getWeaponID() == searchByID) 
      { 
       //Print out the details from the list. 
       cout << "------------------------------------------\n"; 
       cout << "Experience:\t\t" << itr.Item().getWeaponID() << "\n"; 
       cout << "First Name:\t\t" << itr.Item().getWeaponName()<< "\n"; 
       cout << "Second Name:\t\t" << itr.Item().getDamage() << "\n"; 
       cout << "Level:\t\t\t" << itr.Item().getWeight() << "\n"; 
       cout << "------------------------------------------\n"; 
       setWeaponName(itr.Item().getWeaponName()); 
      } 
     } 

    cout << "Weapon NAme: " << getWeaponName(); 
    return getWeaponName(); 
}
