我在模板化优先级队列的头文件中有这个;
template <typename ElemType>
class HeapPQueue {
public:
HeapPQueue<ElemType>();
~HeapPQueue<ElemType>();
ETC
这在cpp文件中;
#include "pqueue-heap.h"
#include "cmpfn.h"
#include "error.h"
using namespace std;
template <typename ElemType>
HeapPQueue<ElemType>::HeapPQueue() {
capacity = START_CAPACITY;
heap = new ElemType[capacity];
logSize = 0;
}
template <typename ElemType>
HeapPQueue<ElemType>::~HeapPQueue() {
delete[] heap;
}
我收到错误消息“未知类型名称 HeapPQueue”。为什么?
