#ifndef STACK_H
#define STACK_H

#include
#include

template
class Stack
{
public:
   Stack();

public:

   void push(const ItemType& item);


   ItemType pop();


   ItemType peek() const;


   void clearStack();

private:

   bool isEmpty() const;


   bool isFull() const;

private:

   static const int maxStackSize = 50;

private:

   ItemType array[maxStackSize];


   int top;
};

template
Stack::Stack() : top(-1)
{}

template
void Stack::push(const ItemType& item)
{
if (isFull())
{
  std::cerr << "Stack overflow!" << std::endl;
  exit(EXIT_FAILURE);
}
top++;
array[top] = item;
}

template
ItemType Stack::pop()
{
if (isEmpty())
{
  std::cerr << "Attempt to pop an empty stack!" << std::endl;
  exit(EXIT_FAILURE);
}
ItemType temp = array[top];
top--;

return temp;
}

template
ItemType Stack::peek() const
{
if (isEmpty())
{
  std::cerr << "Attempt to peek an empty stack!" << std::endl;
  exit(EXIT_FAILURE);
}
return array[top];
}

template
bool Stack::isEmpty() const
{
return (top == -1 ? true : false);
}

template
bool Stack::isFull() const
{
return (top == (maxStackSize - 1) ? true : false);
}

template
void Stack::clearStack()
{
//将所有元素弹出栈
while (!isEmpty())
{
  pop();
}
}

#endif   //STACK_H调用的方法，如下：
#include

#include"stack.h"

int main()
{
Stack charStack;
charStack.push('h');
charStack.peek();
charStack.pop();
charStack.clearStack();

return EXIT_SUCCESS;
}
