写一个单向链表存放员工name,age,gender,要求增删改查的源码

以下是单向链表存放员工信息的源码，包括增删改查功能：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

// 定义员工结构体
typedef struct Employee {
    char name[20];
    int age;
    char gender[10];
    struct Employee *next;
} Employee;

// 创建新员工节点
Employee *createEmployee(char *name, int age, char *gender) {
    Employee *newEmployee = (Employee *)malloc(sizeof(Employee));
    strcpy(newEmployee->name, name);
    newEmployee->age = age;
    strcpy(newEmployee->gender, gender);
    newEmployee->next = NULL;
    return newEmployee;
}

// 在链表末尾添加新员工
void addEmployee(Employee **head, Employee *newEmployee) {
    if (*head == NULL) {
        *head = newEmployee;
    } else {
        Employee *current = *head;
        while (current->next != NULL) {
            current = current->next;
        }
        current->next = newEmployee;
    }
}

// 根据员工姓名查找员工
Employee *findEmployeeByName(Employee *head, char *name) {
    Employee *current = head;
    while (current != NULL) {
        if (strcmp(current->name, name) == ) {
            return current;
        }
        current = current->next;
    }
    return NULL;
}

// 根据员工姓名删除员工
void deleteEmployeeByName(Employee **head, char *name) {
    Employee *current = *head;
    Employee *previous = NULL;
    while (current != NULL) {
        if (strcmp(current->name, name) == ) {
            if (previous == NULL) {
                *head = current->next;
            } else {
                previous->next = current->next;
            }
            free(current);
            return;
        }
        previous = current;
        current = current->next;
    }
}

// 根据员工姓名修改员工信息
void updateEmployeeByName(Employee *head, char *name, int age, char *gender) {
    Employee *employee = findEmployeeByName(head, name);
    if (employee != NULL) {
        employee->age = age;
        strcpy(employee->gender, gender);
    }
}

// 打印所有员工信息
void printAllEmployees(Employee *head) {
    Employee *current = head;
    while (current != NULL) {
        printf("Name: %s, Age: %d, Gender: %s\n", current->name, current->age, current->gender);
        current = current->next;
    }
}

int main() {
    Employee *head = NULL;
    addEmployee(&head, createEmployee("Tom", 25, "Male"));
    addEmployee(&head, createEmployee("Mary", 30, "Female"));
    addEmployee(&head, createEmployee("John", 28, "Male"));
    printf("All employees:\n");
    printAllEmployees(head);
    printf("\n");
    printf("Find employee by name:\n");
    Employee *employee = findEmployeeByName(head, "Mary");
    if (employee != NULL) {
        printf("Name: %s, Age: %d, Gender: %s\n", employee->name, employee->age, employee->gender);
    } else {
        printf("Employee not found.\n");
    }
    printf("\n");
    printf("Delete employee by name:\n");
    deleteEmployeeByName(&head, "Mary");
    printAllEmployees(head);
    printf("\n");
    printf("Update employee by name:\n");
    updateEmployeeByName(head, "John", 29, "Male");
    printAllEmployees(head);
    return ;
}

以上是单向链表存放员工信息的源码，包括增删改查功能。
