Classes template

Bonjour

J'ai une classe template permettant de gérer des piles, mais elle ne fonctionne pas comme il faut, j'ai toujours la même erreur à la compilation

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

#ifndef _STACK_H_ #define _STACK_H_   template<class T> struct StackItem { StackItem<T> *prev; T val; };   template<class T> class Stack { StackItem<T> *first; unsigned int len; public: Stack(); Stack(T first); void Append(T item); void Del(); T* Get(); unsigned int Length(); T* Pop(); };   #include "stack.cpp" #endif

---

Stack.cpp contient les définitions des méthodes

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

#ifdef _STACK_H_   template<class T> Stack<T>::Stack() { this->len = 0; this->first = NULL; }   template<class T> Stack<T>::Stack(T first) { StackItem<T> *f; f->val = first; f->prev = NULL; this->len = 1; this->first = f; }//[...]

---

Je crée mon instance comme suit:

Code:

---

Stack<unsigned int> while_pos();

---

main.cpp:108: error: request for member `Append' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'

main.cpp:111: error: request for member `Get' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'
main.cpp:117: error: request for member `Del' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'

main.cpp:138: error: request for member `Length' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'

main.cpp:141: error: request for member `Length' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'

main.cpp:142: error: request for member `Length' in `while_pos', which is of non-class type `Stack<unsigned int> ()()'

Les utilisations se font à l'intérieur d'un switch

Code:

---

while_pos.Append((unsigned int)f.tellg()); //ligne 108

---

Code:

---

*wpos = while_pos.Get(); //ligne 111

---

Code:

---

while_pos.Del(); //ligne 117

---

Code:

---

if(while_pos.Length() > 0) { //ligne 138

---

Les lignes 141 et 142 sont des appels à Stack<unsigned int>::Length de la forme:

Code:

---

while_pos.Length()

---

[EDIT]J'utilise Dev-C++

Citation:

---

Code:

---

Stack<unsigned int> while_pos();

Ceci est une déclaration de fonction. Oublie les parenthèses si tu veux déclarer une instance.

Erreur idiote, oublié de supprimer les parenthèses après avoir enlevé l'argument
Merci
