4.编制职工档案管理程序 用C语言编制某单位的职工档案管理程序(职工不超过200人),每个职工档案的基本数据项包括职工号、姓名、性别、年龄、部门、住址、基本工资、文化程度等,其他项目可根据需要自行设定。 要求在程序中用不同的函数完成以下各功能要求: (1)从键盘输入这些数据,并按职工号从小到大的顺序保存到文件 zgzl.dat 中(格式自定,但要包含以上各项信息)。 (2)可根据职工姓名查找并输出该职工的档案。 (3)可按部门打印出某个部门的职工工资表(包含职工号、姓名、基本工资等项),并查找出全厂中基本工资最高的职工和基本工资最低的职工。 (4)打印全厂职工的年龄分布情况(包括<35岁、36~45岁、46~55岁、>55岁各年龄段的人数)。

C语言编制的职工管理程序
以下是实现以上功能要求的C语言代码:
```c
#include <stdio.h>

#include <string.h>

int id;
char name[20];
char gender[5];
int age;
char department[20];
char address[50];
float salary;
char education[20];
} Employee;
// 函数声明
int menu();
void input(Employee *employees, int *count);
void save(Employee *employees, int count);
void searchByName(Employee *employees, int count);
void printByDepartment(Employee *employees, int count);
void printSalary(Employee *employees, int count);
void printAgeDistribution(Employee *employees, int count);

注意:以上代码中使用了二进制文件来保存职工档案信息,这样可以方便地读写整个职工档案数组,但是也存在风险,如果数据被损坏或篡改,整个职工档案信息可能会受到影响。因此,在实际应用中,可能需要进行更严格的数据安全措施。
