当然可以！下面是将上述人事管理系统的功能改写成C语言版本的完整代码示例。由于C语言本身不具备像Python那样的面向对象特性，因此我们通过结构体和函数指针模拟类似的功能。 以下是完整的代码： ```c #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAX_NAME_LENGTH 50 typedef struct { char name[MAX_NAME_LENGTH]; int employee_id; } Employee; typedef struct { Employee base; double annual_salary; } FullTimeEmployee; typedef struct { Employee base; double hourly_wage; double hours_worked; } PartTimeEmployee; double calculate_full_time_salary(void* obj) { FullTimeEmployee* emp = (FullTimeEmployee*)obj; return emp->annual_salary / 12.0; } double calculate_part_time_salary(void* obj) { PartTimeEmployee* emp = (PartTimeEmployee*)obj; return emp->hourly_wage * emp->hours_worked; } void add_employee(Employee*** list, size_t* count, void* new_employee, double (*calc_salary)(void*)) { // 扩展数组大小 *list = realloc(*list, sizeof(Employee*) * ((*count) + 1)); // 存储新的员工记录 (*list)[*count] = malloc(sizeof(Employee)); memcpy((*list)[*count], &((Employee*)new_employee)->base, sizeof(Employee)); printf("成功添加 %s 的工资为 %.2f\n", (*list)[*count]->name, calc_salary(new_employee)); (*count)++; } void display_employees(Employee** list, size_t count, double (**salaries)(void*)) { for (size_t i = 0; i < count; ++i) { printf("员工 %d: 名字 - %s, 工资 - %.2f\n", i + 1, list[i]->name, salaries[i](list[i])); } } int main() { Employee** employees = NULL; size_t employee_count = 0; double (*calculators[10])(void*); while (1) { printf("\n人事管理系统:\n"); printf("1. 添加全职员工\n"); printf("2. 添加兼职员工\n"); printf("3. 查看所有员工及薪资\n"); printf("4. 退出\n"); int choice; printf("请选择操作 (1-4): "); scanf("%d", &choice); if (choice == 1) { FullTimeEmployee fte; printf("请输入全职员工姓名: "); scanf("%s", fte.base.name); printf("请输入全职工号: "); scanf("%d", &fte.base.employee_id); printf("请输入年收入: "); scanf("%lf", &fte.annual_salary); calculators[employee_count] = calculate_full_time_salary; add_employee(&employees, &employee_count, &fte, calculate_full_time_salary); } else if (choice == 2) { PartTimeEmployee pte; printf("请输入兼职员工姓名: "); scanf("%s", pte.base.name); printf("请输入兼职工号: "); scanf("%d", &pte.base.employee_id); printf("请输入时薪: "); scanf("%lf", &pte.hourly_wage); printf("请输入工作小时数: "); scanf("%lf", &pte.hours_worked); calculators[employee_count] = calculate_part_time_salary; add_employee(&employees, &employee_count, &pte, calculate_part_time_salary); } else if (choice == 3) { if (employee_count > 0) { display_employees(employees, employee_count, calculators); } else { printf("目前没有任何员工。\n"); } } else if (choice == 4) { break; } else { printf("无效的选择，请重试!\n"); } } // 清理内存 for (size_t i = 0; i < employee_count; i++) { free(employees[i]); } free(employees); printf("感谢使用本系统!\n"); return 0; } ``` --- ### 功能说明： 1. 使用了 `struct` 来定义不同类型的数据存储模型（如全职、兼职员工）； 2. 利用函数指针实现了动态的行为切换，即对于不同类型的员工有不同的工资计算逻辑； 3. 提供了一个简单的命令行界面用于交互。 ---
