What's wrong with this?

What''s wrong with this code? #include //#include "List.cpp" //using namespace std; //introduces namespace std class Bullet { public: Bullet *prev; Bullet *next; Bullet () {}; Bullet (/*POINT location,*/ double direction, int type); void doAI(); //Bullet returnNext(); //Bullet returnPrev(); }; Bullet::Bullet (/*POINT location,*/ double direction, int type) { cout << "new Bullet created" << direction << type; } void Bullet::doAI() { cout << "Doing AI..."; } /*Bullet Bullet::returnNext() { return *next; } Bullet Bullet::returnPrev() { return *prev; }*/ class List { private: Bullet *FirstBullet; Bullet *LastBullet; public: List(); List(Bullet *aBullet); ~List(); void doAI(); Bullet* AddBullet(/*LPoint location,*/ double direction, int type); void RemoveBullet(Bullet *aBullet); }; List::List() { FirstBullet = NULL; LastBullet = NULL; } List::List(Bullet *aBullet) { FirstBullet = aBullet; LastBullet = aBullet; } void List::doAI() { Bullet *temp_bullet; Bullet *temp_next; temp_bullet = FirstBullet; while(temp_bullet != NULL) { temp_next = temp_bullet->next; temp_bullet->doAI(); temp_bullet = temp_next; } } Bullet* List::AddBullet(/*POINT location,*/ double direction, int type) { Bullet *newBullet; newBullet = new Bullet(/*location,*/ direction, type); if (LastBullet == NULL) { FirstBullet =LastBullet = newBullet; } else { LastBullet->next = newBullet; newBullet->prev = LastBullet; LastBullet = newBullet; } return newBullet; } void List::RemoveBullet(Bullet *aBullet) { if (FirstBullet == aBullet) { Bullet *temp_next; temp_next = aBullet->next; temp_next->prev = NULL; FirstBullet = temp_next; delete aBullet; } else if (LastBullet == aBullet) { Bullet *temp_prev; temp_prev = aBullet->prev; temp_prev->next = NULL; delete aBullet; } else { Bullet *temp_prev; Bullet *temp_next; temp_prev = aBullet->prev; temp_next = aBullet->next; temp_prev->next = temp_next; temp_next->prev = temp_prev; delete aBullet; } } List::~List() { Bullet *temp_bullet; Bullet *temp_next; temp_bullet = FirstBullet; while(temp_bullet != NULL) { temp_next = temp_bullet->next; RemoveBullet(temp_bullet); temp_bullet = temp_next; } } void main () { Bullet *temp_bullet; /*LPoint tempPoint;*/ int temptype, tempX, tempY; double tempDouble; List myList; cout << "How many Bullets to create? "; int input; cin >> input; for (int i = 1; i<=input; i++) { cout << "\nInput x location for bullet#" << i; cin >> tempX; cout << "\nInput y location for bullet#" << i; cin >> tempY; /*tempPoint.x = tempX; tempPoint.y = tempY;*/ cout << "\nInput direction for bullet#" << i; cin >> tempDouble; cout << "\nInput type number for bullet#" << i; cin >> temptype; temp_bullet = myList.AddBullet(/*tempPoint, */tempDouble, temptype); } myList.doAI(); //return 0; } It performs an illegal operation (try compiling it). I have no idea what could be the problem because it seems right to me. E-mail: chaos1111@hotmail.com me (Mark)

Thanx, it works great now.
