我正在尝试使用模板创建一个类linkedList,但是当我编译它时,IDE 给出了一个错误: undefined reference to `listType::add(int) 我不明白为什么?
链接列表.h
#ifndef LINKEDLISTS_H_INCLUDED
#define LINKEDLISTS_H_INCLUDED
#include "struct.h"
template <class type1>
class listType
{
public:
void add(type1);
void print();
private:
node<type1> *head;
};
#endif // LINKEDLISTS_H_INCLUDED
链表.cpp
#include "linkedLists.h"
#include "struct.h"
#include <iostream>
using namespace std;
template <class type1>
void listType<type1>::add(type1 temp)
{
node<type1> *t;
t->value=temp;
t->link=head;
head=t;
}
template <class type1>
void listType<type1>::print()
{
node<type1> *p;
p=head;
while(p!=NULL)
{
cout<<p->value<<endl;
p=p->link;
}
}
结构体.h
#ifndef STRUCT_H_INCLUDED
#define STRUCT_H_INCLUDED
template <class type1>
struct node
{
type1 value;
node *link;
};
#endif // STRUCT_H_INCLUDED
主文件
#include <iostream>
#include "linkedLists.h"
using namespace std;
int main()
{
listType <int> test;
test.add(5);
}
