用c语言写学院教学管理系统

学院教学管理系统通常是一个复杂的系统，需要多个模块协同工作。下面是一个基本的C语言实现，仅供参考：

1. 教师模块

// 定义教师结构体
struct Teacher {
    char name[20];
    char id[10];
    char course[20];
};

// 添加教师信息
void add_teacher(struct Teacher *teachers, int *count) {
    printf("请输入教师姓名：");
    scanf("%s", teachers[*count].name);
    printf("请输入教师编号：");
    scanf("%s", teachers[*count].id);
    printf("请输入教授课程：");
    scanf("%s", teachers[*count].course);
    (*count)++;
}

// 删除教师信息
void delete_teacher(struct Teacher *teachers, int *count) {
    char id[10];
    printf("请输入要删除的教师编号：");
    scanf("%s", id);
    for (int i = 0; i < *count; i++) {
        if (strcmp(teachers[i].id, id) == 0) {
            for (int j = i; j < *count - 1; j++) {
                teachers[j] = teachers[j + 1];
            }
            (*count)--;
            printf("删除成功！\n");
            return;
        }
    }
    printf("未找到该教师！\n");
}

// 查询教师信息
void search_teacher(struct Teacher *teachers, int count) {
    char id[10];
    printf("请输入要查询的教师编号：");
    scanf("%s", id);
    for (int i = 0; i < count; i++) {
        if (strcmp(teachers[i].id, id) == 0) {
            printf("教师姓名：%s\n", teachers[i].name);
            printf("教师编号：%s\n", teachers[i].id);
            printf("教授课程：%s\n", teachers[i].course);
            return;
        }
    }
    printf("未找到该教师！\n");
}

2. 学生模块

// 定义学生结构体
struct Student {
    char name[20];
    char id[10];
    int age;
    char sex[5];
    float score;
};

// 添加学生信息
void add_student(struct Student *students, int *count) {
    printf("请输入学生姓名：");
    scanf("%s", students[*count].name);
    printf("请输入学生编号：");
    scanf("%s", students[*count].id);
    printf("请输入学生年龄：");
    scanf("%d", &students[*count].age);
    printf("请输入学生性别：");
    scanf("%s", students[*count].sex);
    printf("请输入学生成绩：");
    scanf("%f", &students[*count].score);
    (*count)++;
}

// 删除学生信息
void delete_student(struct Student *students, int *count) {
    char id[10];
    printf("请输入要删除的学生编号：");
    scanf("%s", id);
    for (int i = 0; i < *count; i++) {
        if (strcmp(students[i].id, id) == 0) {
            for (int j = i; j < *count - 1; j++) {
                students[j] = students[j + 1];
            }
            (*count)--;
            printf("删除成功！\n");
            return;
        }
    }
    printf("未找到该学生！\n");
}

// 查询学生信息
void search_student(struct Student *students, int count) {
    char id[10];
    printf("请输入要查询的学生编号：");
    scanf("%s", id);
    for (int i = 0; i < count; i++) {
        if (strcmp(students[i].id, id) == 0) {
            printf("学生姓名：%s\n", students[i].name);
            printf("学生编号：%s\n", students[i].id);
            printf("学生年龄：%d\n", students[i].age);
            printf("学生性别：%s\n", students[i].sex);
            printf("学生成绩：%f\n", students[i].score);
            return;
        }
    }
    printf("未找到该学生！\n");
}

3. 主函数

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

#include "teacher.h"
#include "student.h"

int main() {
    struct Teacher teachers[100];
    struct Student students[100];
    int teacher_count = 0;
    int student_count = 0;
    int choice;

    while (1) {
        printf("请选择操作：\n");
        printf("1. 添加教师信息\n");
        printf("2. 删除教师信息\n");
        printf("3. 查询教师信息\n");
        printf("4. 添加学生信息\n");
        printf("5. 删除学生信息\n");
        printf("6. 查询学生信息\n");
        printf("0. 退出\n");
        scanf("%d", &choice);

        switch (choice) {
            case 1:
                add_teacher(teachers, &teacher_count);
                break;
            case 2:
                delete_teacher(teachers, &teacher_count);
                break;
            case 3:
                search_teacher(teachers, teacher_count);
                break;
            case 4:
                add_student(students, &student_count);
                break;
            case 5:
                delete_student(students, &student_count);
                break;
            case 6:
                search_student(students, student_count);
                break;
            case 0:
                return 0;
            default:
                printf("无效的操作！\n");
                break;
        }
    }
}

注意，上述代码仅是一个简单的示例，实际的学院教学管理系统会更加复杂。在实现时需要仔细考虑各种情况，并且需要使用合适的数据结构来存储和管理数据。
