使用c++语言编写一个程序，要求如下 建立一个节点包括职工的编号，年龄，和性别的信息的单向链表，分别定义函数完成以下功能：1.遍历该链表输出全部职工信息。2.分别统计男女职工的人数。3.在链表尾部插入新职工结点。4.删除指定编号的职工结点。5.删除年龄在60岁以上的男职工或55岁以上的女职工结点，并保存在另一个链表中，要求用主函数建立简单菜单选择，并测试程序

好的，下面是我为您提供的代码，希望能够帮到您。

#include <iostream>

using namespace std;

struct Employee {
    int id; // 职工编号
    int age; // 职工年龄
    char gender; // 职工性别
    Employee* next; // 指向下一个节点的指针
};

class EmployeeList {
public:
    EmployeeList() {
        head = NULL;
        maleCount = 0;
        femaleCount = 0;
    }

    // 遍历链表并输出所有职工信息
    void traverse() {
        Employee* p = head;
        while (p != NULL) {
            cout << "ID: " << p->id << ", Age: " << p->age << ", Gender: " << p->gender << endl;
            p = p->next;
        }
    }

    // 统计男女职工的人数
    void countGender() {

                femaleCount++;
            }
            p = p->next;
        }
        cout << "Male count: " << maleCount << ", Female count: " << femaleCount << endl;
