遍历链表.h文件和.cpp用case输出应该怎么写？

下面是遍历链表的.h和.cpp文件的代码，可以使用switch case语句输出：

链表头文件 LinkedList.h：

#ifndef LINKEDLIST_H
#define LINKEDLIST_H

#include <iostream>

struct Node {
    int data;
    Node* next;
};

class LinkedList {
public:
    LinkedList();
    ~LinkedList();
    void insert(int value);
    void remove(int value);
    void print();

private:
    Node* head;
};

#endif // LINKEDLIST_H

链表源文件 LinkedList.cpp：

#include "LinkedList.h"

LinkedList::LinkedList() {
    head = nullptr;
}

LinkedList::~LinkedList() {
    Node* current = head;
    while (current != nullptr) {
        Node* next = current->next;
        delete current;
        current = next;
    }
}

void LinkedList::insert(int value) {
    Node* newNode = new Node;
    newNode->data = value;
    newNode->next = head;
    head = newNode;
}

void LinkedList::remove(int value) {
    Node* current = head;
    Node* previous = nullptr;
    while (current != nullptr) {
        if (current->data == value) {
            if (previous == nullptr) {
                head = current->next;
            } else {
                previous->next = current->next;
            }
            delete current;
            return;
        }
        previous = current;
        current = current->next;
    }
}

void LinkedList::print() {
    Node* current = head;
    while (current != nullptr) {
        std::cout << current->data << " ";
        current = current->next;
    }
    std::cout << std::endl;
}

使用switch case输出链表.h和.cpp文件的代码：

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::ifstream hFile("LinkedList.h");
    std::ifstream cppFile("LinkedList.cpp");
    std::string line;
    int fileIndex = 0;

    while (getline(hFile, line)) {
        switch (fileIndex) {
            case 0:
                std::cout << "// 链表头文件 LinkedList.h：" << std::endl;
                break;
            case 1:
                std::cout << "// 链表源文件 LinkedList.cpp：" << std::endl;
                break;
        }
        std::cout << line << std::endl;
        if (line.find("#endif") != std::string::npos) {
            ++fileIndex;
        }
    }

    while (getline(cppFile, line)) {
        switch (fileIndex) {
            case 1:
                std::cout << "// 链表头文件 LinkedList.h：" << std::endl;
                break;
            case 2:
                std::cout << "// 链表源文件 LinkedList.cpp：" << std::endl;
                break;
        }
        std::cout << line << std::endl;
        if (line.find("void LinkedList::print()") != std::string::npos) {
            ++fileIndex;
        }
    }

    hFile.close();
    cppFile.close();

    return 0;
}

其中，fileIndex变量表示当前正在处理的文件的索引。当读取到`.h`文件的`#endif`预处理指令时，fileIndex加1，表示开始读取`.cpp`文件；当读取到`.cpp`文件的`void LinkedList::print()`函数定义时，fileIndex再次加1，表示`.cpp`文件处理完毕。在switch case语句中，根据fileIndex的值输出对应的注释和代码。
