用C语言编写一个学生宿舍管理系统

好的，下面是一个简单的学生宿舍管理系统的C语言代码示例：

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

#define MAX_STUDENTS 100
#define MAX_NAME_LEN 20

typedef struct {
    char name[MAX_NAME_LEN];
    int room_num;
} Student;

Student students[MAX_STUDENTS];
int num_students = 0;

void add_student() {
    if (num_students >= MAX_STUDENTS) {
        printf("Error: Maximum number of students reached.\n");
        return;
    }
    printf("Enter student name: ");
    scanf("%s", students[num_students].name);
    printf("Enter room number: ");
    scanf("%d", &students[num_students].room_num);
    num_students++;
    printf("Student added.\n");
}

void remove_student() {
    char name[MAX_NAME_LEN];
    printf("Enter student name: ");
    scanf("%s", name);
    int found = 0;
    for (int i = 0; i < num_students; i++) {
        if (strcmp(students[i].name, name) == 0) {
            found = 1;
            for (int j = i; j < num_students - 1; j++) {
                strcpy(students[j].name, students[j+1].name);
                students[j].room_num = students[j+1].room_num;
            }
            num_students--;
            printf("Student removed.\n");
            break;
        }
    }
    if (!found) {
        printf("Error: Student not found.\n");
    }
}

void list_students() {
    printf("Student list:\n");
    for (int i = 0; i < num_students; i++) {
        printf("%s\t%d\n", students[i].name, students[i].room_num);
    }
}

int main() {
    int choice;
    do {
        printf("\n1. Add student\n");
        printf("2. Remove student\n");
        printf("3. List students\n");
        printf("4. Exit\n");
        printf("Enter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1: add_student(); break;
            case 2: remove_student(); break;
            case 3: list_students(); break;
            case 4: break;
            default: printf("Error: Invalid choice.\n");
        }
    } while (choice != 4);

    return 0;
}

这个程序包括添加、删除和列出学生的功能。你可以根据实际需要进行修改和扩展。
