企业员工管理系统c语言

企业员工管理系统是一个比较复杂的系统，需要涉及到数据库操作、用户界面设计等方面的知识。以下是一个简单的C语言代码示例，用于演示如何实现一个基本的员工管理系统。

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

#define MAX_SIZE 1000

struct Employee {
    int id;
    char name[20];
    int age;
    double salary;
};

struct Employee employees[MAX_SIZE];
int num_employees = 0;

void add_employee() {
    if (num_employees >= MAX_SIZE) {
        printf("The employee list is full.\n");
        return;
    }

    struct Employee new_employee;

    printf("Enter the employee ID: ");
    scanf("%d", &new_employee.id);

    printf("Enter the employee name: ");
    scanf("%s", new_employee.name);

    printf("Enter the employee age: ");
    scanf("%d", &new_employee.age);

    printf("Enter the employee salary: ");
    scanf("%lf", &new_employee.salary);

    employees[num_employees] = new_employee;
    num_employees++;

    printf("Employee added successfully.\n");
}

void list_employees() {
    printf("ID\tName\tAge\tSalary\n");

    for (int i = 0; i < num_employees; i++) {
        printf("%d\t%s\t%d\t%.2lf\n",
               employees[i].id,
               employees[i].name,
               employees[i].age,
               employees[i].salary);
    }
}

void search_employee() {
    int id;

    printf("Enter the employee ID to search: ");
    scanf("%d", &id);

    for (int i = 0; i < num_employees; i++) {
        if (employees[i].id == id) {
            printf("ID\tName\tAge\tSalary\n");
            printf("%d\t%s\t%d\t%.2lf\n",
                   employees[i].id,
                   employees[i].name,
                   employees[i].age,
                   employees[i].salary);
            return;
        }
    }

    printf("Employee not found.\n");
}

void delete_employee() {
    int id;

    printf("Enter the employee ID to delete: ");
    scanf("%d", &id);

    for (int i = 0; i < num_employees; i++) {
        if (employees[i].id == id) {
            for (int j = i; j < num_employees - 1; j++) {
                employees[j] = employees[j + 1];
            }
            num_employees--;
            printf("Employee deleted successfully.\n");
            return;
        }
    }

    printf("Employee not found.\n");
}

int main() {
    int choice;

    while (1) {
        printf("1. Add employee\n");
        printf("2. List employees\n");
        printf("3. Search employee\n");
        printf("4. Delete employee\n");
        printf("5. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_employee();
                break;
            case 2:
                list_employees();
                break;
            case 3:
                search_employee();
                break;
            case 4:
                delete_employee();
                break;
            case 5:
                printf("Goodbye!\n");
                exit(0);
            default:
                printf("Invalid choice. Please try again.\n");
                break;
        }
    }

    return 0;
}

这个程序实现了以下功能：

- 添加员工信息
- 列出所有员工信息
- 搜索员工信息
- 删除员工信息

你可以根据自己的需求，对这个程序进行修改和扩展。
