c++ - 使用节点类

Question

node *temp; 
temp->dataItem = newPassenger;
if(size == 0)
{
    Head = temp;
    Tail = temp;
}
else
{
    Tail->nextNode = temp;
    Tail = temp;
}
size++;

我需要帮助，因为 VS 一直说 temp 未初始化，我对 C++ 没有什么经验。我的节点类如下

#include "passenger.h"
#pragma once
class node
{
public:
    node();
    passenger dataItem;
    node * nextNode;
};

Answer 1

node *temp = new node; 
temp->dataItem = newPassenger;
if(size == 0)
{
    Head = temp;
    Tail = temp;
}
else
{
    Tail->nextNode = temp;
    Tail = temp;
}
size++;
