我正在尝试使某种模板Queue
类。这似乎确定,但我得到2错误在同一行,我不明白为什么。这些错误出现在实现文件.cpp中,我试图给析构函数定义。下面是类的头文件的代码:错误:在'<'token之前预期的非限定id
#ifndef QUEUETP_H_INCLUDED
#define QUEUETP_H_INCLUDED
template <class T>
class QueueTp
{
private:
struct Node { T item; struct Node * next;};
enum {QSIZE = 10};
//Queue's head
Node *head;
//Queue's tail
Node *tail;
int size;
int maxsize;
QueueTp(const QueueTp & q);
QueueTp & operator=(const QueueTp & q) { return *this;}
public:
QueueTp(): size(0),head(0),tail(0),maxsize(QSIZE) {};
QueueTp(int q = QSIZE): size(0),head(0),tail(0),maxsize(q) {};
~QueueTp();
bool isEmpty(){return size==0;}
bool isFull() {return size==maxsize;}
int sizecur() {return size;}
bool push(const T& t);
bool pop(T& t);
};
#include "QueueTp.cpp"
#endif // QUEUETP_H_INCLUDED
,这里是在执行文件中的析构函数的定义:
#include "QueueTp.h"
#include <iostream>
using namespace std;
typename <class T> //<-<-<- in this line I am getting the two errors
QueueTp<class T>::~QueueTp()
{
Node *ptr;
cout<<endl<<"Deleting the queue...";
while (head !=NULL)
{
ptr = head->next;
delete head;
head = ptr;
}
}
//......other method definitions
的错误,指出上面和具体的错误消息我从编译器得到的是下面的。
error: expected nested-name-specifier before ‘<’ token|
error: expected unqualified-id before ‘<’ token|

我可以删除莫名其妙的愚蠢问题。我感到尴尬。 – 2011-12-21 20:22:06
是的,你的问题底部应该有一个'删除'链接。 : - ] – ildjarn 2011-12-21 20:22:42
