如何通过带头结点的链表实现单词本管理,单词本按首字母由小到大顺序排列(在形成链表的过程中完成排序)。输出当前链表中所有的英文单词和相应的中文解释。

首先,我们需要定义一个带头结点的链表节点结构体,包含单词和中文解释两个字段:
```c++
struct WordNode {
string word;
string meaning;
WordNode* next;
};
```
然后,我们可以实现一个函数,用于向链表中插入新的单词节点,并保证链表按照首字母由小到大的顺序排列:
```c++
void insertWord(WordNode* head, string word, string meaning) {
WordNode* newNode = new WordNode;
newNode->word = word;
newNode->meaning = meaning;
newNode->next = nullptr;
WordNode* prev = head;
WordNode* curr = head->next;
while (curr && curr->word < word) {
prev = curr;
curr = curr->next;
}
prev->next = newNode;
newNode->next = curr;
}
```
最后,我们可以实现一个函数,遍历链表并输出所有的英文单词和相应的中文解释:
```c++
void printWordList(WordNode* head) {
WordNode* curr = head->next;
while (curr) {
cout << curr->word << ":" << curr->meaning << endl;
curr = curr->next;
}
}
```
完整代码如下:
```c++
#include <iostream>
#include <string>
using namespace std;
struct WordNode {
string word;
string meaning;
WordNode* next;
};
void insertWord(WordNode* head, string word, string meaning) {
WordNode* newNode = new WordNode;
newNode->word = word;
newNode->meaning = meaning;
newNode->next = nullptr;
WordNode* prev = head;
WordNode* curr = head->next;
while (curr && curr->word < word) {
prev = curr;
curr = curr->next;
}
prev->next = newNode;
newNode->next = curr;
}
void printWordList(WordNode* head) {
WordNode* curr = head->next;
while (curr) {
cout << curr->word << ":" << curr->meaning << endl;
curr = curr->next;
}
}
int main() {
WordNode* head = new WordNode;
head->next = nullptr;
insertWord(head, "apple", "苹果");
insertWord(head, "banana", "香蕉");
insertWord(head, "cherry", "樱桃");
insertWord(head, "orange", "橙子");
printWordList(head);
return 0;
}
```
