人事管理系统演示c语言，人事管理系统C语言演示

人事管理系统的C语言演示可以分为以下几个部分：

1. 系统初始化

2. 员工信息管理

3. 考勤管理

4. 工资计算

5. 报表生成

6. 系统退出

下面是一个简单的C语言实现的人事管理系统示例代码：

```c

#include

#include

#include

typedef struct {

char name[20];

int id;

float salary;

} Employee;

typedef struct {

int employee_count;

Employee employees[100];

} HRSystem;

void initialize_system(HRSystem *hrs) {

hrs->employee_count = 0;

for (int i = 0; i < 100; i++) {

strcpy(hrs->employees[i].name, "");

hrs->employees[i].id = 0;

hrs->employees[i].salary = 0.0;

}

}

void add_employee(HRSystem *hrs, char *name, int id, float salary) {

strcpy(hrs->employees[hrs->employee_count].name, name);

hrs->employees[hrs->employee_count].id = id;

hrs->employees[hrs->employee_count].salary = salary;

hrs->employee_count++;

}

void delete_employee(HRSystem *hrs, int id) {

for (int i = 0; i < hrs->employee_count; i++) {

if (hrs->employees[i].id == id) {

for (int j = i; j < hrs->employee_count
• 1; j++) {

strcpy(hrs->employees[j + 1].name, hrs->employees[j].name);

hrs->employees[j + 1].id = hrs->employees[j].id;

hrs->employees[j + 1].salary = hrs->employees[j].salary;

}

hrs->employee_count--;

return;

}

}

printf("No employee with ID %d found.n", id);

}

void update_employee(HRSystem *hrs, int id, char *name, float salary) {

for (int i = 0; i < hrs->employee_count; i++) {

if (hrs->employees[i].id == id) {

strcpy(hrs->employees[i].name, name);

hrs->employees[i].salary = salary;

return;

}

}

printf("No employee with ID %d found.n", id);

}

void display_employees(HRSystem *hrs) {

for (int i = 0; i < hrs->employee_count; i++) {

printf("ID: %d, Name: %s, Salary: %.2fn", hrs->employees[i].id, hrs->employees[i].name, hrs->employees[i].salary);

}

}

int main() {

HRSystem hrs;

initialize_system(&hrs);

add_employee(&hrs, "张三", 1, 5000.0);

add_employee(&hrs, "李四", 2, 6000.0);

add_employee(&hrs, "王五", 3, 7000.0);

display_employees(&hrs);

update_employee(&hrs, 1, "张三", 5500.0);

display_employees(&hrs);

delete_employee(&hrs, 2);

display_employees(&hrs);

return 0;

}

```

这个示例代码实现了一个简单的人事管理系统，包括员工信息的添加、删除、更新和显示功能。你可以根据需要扩展这个系统，例如增加请假、加班、出差等操作。
