求大神帮忙调试一下

贴代码，

#ifndef QUEUETP_H
#define QUEUETP_H

template< class Item >
class QueueTP
{
private:
	enum{ Q_SIZE = 10 };
	class Node
	{
	public:
		Item item;
		Node *next;
		Node( const Item & i ) : item(i), next(0) {}
	};
	Node * front;
	Node *rear;
	int items;
	const int qsize;
	QueueTP( const QueueTP & q ): qsize(0) {}
	QueueTP & operator=( const QueueTP & q ) { return *this; }

public:
	QueueTP(int qs = Q_SIZE);
    ~QueueTP();
	bool isempty() const
	{
		return items==0;
	}
	bool isfull() const
	{
		return items== qsize;
	}

	int queuecount() const
	{
		return items;
	}

	bool enqueue(const Item &item);
	bool dequeue(Item & item);
};

template <class Item>
QueueTP<Item>::QueueTP(int qs): qsize(qs)
{
	front = rear = 0;
	items=0;
}

template<class Item>
QueueTP<Item>::~QueueTP()
{
	Node * temp;
	while( front != 0 )
	{
      temp=front;
	  front = front->next;
	  delete temp;
	}
}

template <class Item>
bool QueueTP<Item>:: enqueue( const Item & item )
{
	if(isfull())
	   return false;
	Node *add = new Node(item);
	items++;
	if(front == 0 )
		front = add;
	else
		rear->next =add;
	rear=add;
	return true;
}
template < class Item>
bool QueueTP<Item>::dequeue(Item & item)
{
	if(front == 0 )
		return false;
	item = front->item;
	item--;
	Node * temp = front;
	front = front->next;
	delete temp;
	if(items == 0 )
		rear = 0;
	return true;
}
#endif

，

#include <iostream>
#include <string>
#include "queuetp.h"

int main()
{
	using std::string;
	using std::cin;
	using std::cout;

	QueueTP<string> cs(5);
	string temp;

	while(!cs.isfull())
	{
		cout<<"Please enter your name. You will be "
			  "served in the order of arrival. \n "
			  "name: ";
		getline(cin, temp);
		cs.enqueue(temp);
	}

	cout<<"The queue is full.Processing begins! \n";

	while(!cs.isempty())
	{
		cs.dequeue(temp);
		cout<<"Now processing "<<temp<< "....\n";

	}
	return 0;
}

。
，出现这个错误，调试不出来，或者说我不会调试。。。。

错误提示很明显，queuetp.h第83行，你的自减运算符“- -”，的两个“-”号之间的空格去掉

[brookmill]

items--;

引用 2 楼 brookmill 的回复:

items--;

正解
