写一个C语言教职工管理系统

好的，下面是一个简单的C语言教职工管理系统，可以添加、删除、查找和显示教职工信息：

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

#define MAX_NAME_LENGTH 50

typedef struct employee {
    char name[MAX_NAME_LENGTH];
    int age;
    float salary;
} Employee;

int num_employees = 0;
Employee employees[100];

void add_employee() {
    if (num_employees >= 100) {
        printf("Maximum number of employees reached!\n");
        return;
    }
    printf("Enter name: ");
    scanf("%s", employees[num_employees].name);
    printf("Enter age: ");
    scanf("%d", &employees[num_employees].age);
    printf("Enter salary: ");
    scanf("%f", &employees[num_employees].salary);
    num_employees++;
}

void delete_employee() {
    char name[MAX_NAME_LENGTH];
    printf("Enter name of employee to delete: ");
    scanf("%s", name);
    for (int i = 0; i < num_employees; i++) {
        if (strcmp(name, employees[i].name) == 0) {
            for (int j = i; j < num_employees - 1; j++) {
                employees[j] = employees[j + 1];
            }
            num_employees--;
            printf("Employee %s deleted!\n", name);
            return;
        }
    }
    printf("Employee %s not found!\n", name);
}

void find_employee() {
    char name[MAX_NAME_LENGTH];
    printf("Enter name of employee to find: ");
    scanf("%s", name);
    for (int i = 0; i < num_employees; i++) {
        if (strcmp(name, employees[i].name) == 0) {
            printf("Employee %s found! Age: %d, Salary: %.2f\n", employees[i].name, employees[i].age, employees[i].salary);
            return;
        }
    }
    printf("Employee %s not found!\n", name);
}

void display_employees() {
    printf("Name\tAge\tSalary\n");
    for (int i = 0; i < num_employees; i++) {
        printf("%s\t%d\t%.2f\n", employees[i].name, employees[i].age, employees[i].salary);
    }
}

int main() {
    int choice;
    do {
        printf("\n1. Add employee\n");
        printf("2. Delete employee\n");
        printf("3. Find employee\n");
        printf("4. Display all employees\n");
        printf("5. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                add_employee();
                break;
            case 2:
                delete_employee();
                break;
            case 3:
                find_employee();
                break;
            case 4:
                display_employees();
                break;
            case 5:
                printf("Goodbye!\n");
                break;
            default:
                printf("Invalid choice!\n");
                break;
        }
    } while (choice != 5);
    return 0;
}

该程序使用结构体 `Employee` 来存储教职工信息，包括姓名、年龄和薪水。程序提供了四个操作：添加教职工、删除教职工、查找教职工和显示所有教职工。程序最多可以管理100个教职工。
