这道有点坑，不太懂怎么构造那个队列模板，下面的仅供参考。

做出来的希望能留言给我看看是怎么实现的

Queue.cpp

//#include <iostream>
//#include "Work.cpp"
//#include <memory>//智能指针模板
//using namespace std;
//为了简化，这个队列我就只定义简单的功能了



template <class T>
class Queue{
private:
	struct Node{//在类里面定义一个结构，用于实现队列中的节点
	T *t;
	Node *next;
	};
	//enum{MAX=10};
	Node *front;
	Node *rear;
	int size;
public:
	Queue()
	{
		front=rear=nullptr;	
		size=0;
	}
	~Queue()
	{
		//T *p=front;
		//while(p!=rear)
			//delete p;
	}
	bool isEmpty()
	{
		return front==nullptr;
	}
	/*	队列长度不设上限
	bool isFull()
	{
		return size==MAX;
	}*/
	bool enQueue(T *t)
	{
		Queue::Node *add=new Queue::Node;
		add->t=t;//需要该类定义一个“=”运算符
		if(isEmpty())
		{
			front=add;
			add->next=nullptr;
			rear=add->next;
			return true;
		}
		else
		{
		rear=add;
		add->next=nullptr;
		rear=add->next;
		return true;
		}
		return false;
}
	T show()
	{
		Node *p=front;
		if(p==rear)
			return rear->t;
		else
		{
			p=p->next;
			return show();
		}
			
	}



};
