Re: Template Specialization

templates.h

  #pragma once

template<class T>

class Stack {

public:

       Stack(int i = 10);

       ~Stack() {delete [] mStackPtr;}

       int push(T value);

       int Pop(T val);

private:

       int size;

       int top;

       T *mStackPtr;

};

template<class T>

Stack<T>::Stack(int i)

{

       top = 0;

       size = i;

       mStackPtr = new T[size];

}

template<class T>

int Stack<T>::push(T value)

{

       mStackPtr[++top] = value;

       return 1;

}

template<class T>

int Stack<T>::Pop(T val)

{

       if (top) {

             val =mStackPtr[top--];

       }

       return 1;

}

// Specializatiom

template<>

class Stack<char>

{

       public:

             int push(char a);

             int Pop(char a);

private:

       int size;

       int top;

       char *mStackPtr;

};

int Stack<char>::push(char value)

{

       mStackPtr[++top] = value;

       return 1;

}

int Stack<char>::Pop(char val)

{

       if (top) {

             val =mStackPtr[top--];

       }

       return 1;

}

SecondFile.cpp

#include"templates.h"

templates.cpp

#include"templates.h"

int main()

{

Stack<int> abc;

abc.push(1);

abc.push(2);

return 0;

}

Why this program is giving linking error

If I remove inclusion in SecondFile .cpp file then it works fine
If remove specialization of Stack class then it works fine
