نحوه استفاده صحیح از template ها

[hafez1]

برنامه ای که کداشو پایین گذاشتم با به کار گیری template نوشته شده.ارور می ده
فک کنم یه جاهایی توی به کار گیری template اشتباه کردم.
برنامه اومده توابع pop و push در stack را به وسیله لینک لیست یک طرفه نوشته.



#include <iostream.h>

template <class Type>

class Stack{

public:
Stack();
~Stack();

void push(Type data);
Type pop();

private:
Type info;
Stack *previous;
};

template <class Type>
Stack<Type> *head;

template <class Type>

int main()
{
head = new Stack<Type>;
Stack stk;
int i, data, numpush, numpop;
cout << "Please enter count push : ";
cin >> numpush;
for(i = 0; i < numpush; i++)
{
cout << "\nPlease enter data (" << i + 1 << ") = ";
cin >> data;
stk.push(data);
}
cout << "\nPlease enter count pop : ";
cin >> numpop;
for(i = 0;i < numpop; i++)
cout << "\npop (" << i + 1 << ") = " << stk.pop();
cout << endl;
return 0;
}

template <class Type>
Stack<Type>::Stack()
{}

template <class Type>
Stack<Type>::~Stack()
{
Stack<Type> *temp = NULL;

while(head->previous != NULL)
{
temp = head->previous;
delete head;head = temp;
}
}

template <class Type> void Stack<Type>::push(Type data)
{
Stack *temp = new Stack<Type>;
temp->info = data;
temp->previous = head;head = temp;
}

template <class Type> Type Stack<Type>::pop(){Type data = 0;

if(head->previous != NULL){Stack<Type> *temp = head;
data = head->info;
head = head->previous;

delete temp;
}

return data;
}

لطفا هرکی می دونه کمکم کنه:بوس:

سلام.
بلاخره مشکلشو فهمیدم. باید نوع را مشخص کنید (Type).
برنامه بدون خطا:

#include <iostream.h>
template <class Type> class Stack
{
public:
Stack();
~Stack();
void push(Type data);
Type pop();
private:
Type info;
Stack<Type>* previous;
};
Stack<char>* head;
int main()
{
head = new Stack<char>;
Stack<char> stk;
char data;
int i, numpush, numpop;
cout << "Please enter count push : ";
cin >> numpush;
for(i = 0; i < numpush; i++)
{
cout << "\nPlease enter data (" << i + 1 << ") = ";
cin >> data;
stk.push(data);
}
cout << "\nPlease enter count pop : ";
cin >> numpop;
for(i = 0; i < numpop; i++)
cout << "\npop (" << i + 1 << ") = " << stk.pop();
cout << endl;
return 0;
}

template <class Type> Stack<Type>::Stack()
{
}

template <class Type> Stack<Type>::~Stack()
{
while(head->previous != NULL)
{
Stack<Type>* temp = head->previous;
delete head;
head = temp;
}
}
template <class Type> void Stack<Type>::push(Type data)
{
Stack<Type>* temp = new Stack<Type>;
temp->info = data;
temp->previous = head;
head = temp;
}
template <class Type> Type Stack<Type>::pop()
{
Type data = 0;
if(head->previous != NULL)
{
Stack<Type>* temp = head->previous;
head->previous = NULL;
data = head->info;
delete head;
head = temp;
}
return data;
}
