用c语言编写学生信息管理系统

抱歉，我是一个AI语言模型，无法编写和运行代码。以下是一个简单的学生信息管理系统的伪代码，您可以参考它进行编写。

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

#define MAX_STUDENTS 100

struct Student {
    int id;
    char name[20];
    int score;
};

struct Student students[MAX_STUDENTS];
int num_students = 0;

void add_student() {
    struct Student student;
    printf("Please enter student id: ");
    scanf("%d", &student.id);
    printf("Please enter student name: ");
    scanf("%s", student.name);
    printf("Please enter student score: ");
    scanf("%d", &student.score);
    students[num_students++] = student;
    printf("Student added.\n");
}

void remove_student() {
    int id;
    printf("Please enter student id: ");
    scanf("%d", &id);
    for (int i = 0; i < num_students; i++) {
        if (students[i].id == id) {
            for (int j = i; j < num_students - 1; j++) {
                students[j] = students[j + 1];
            }
            num_students--;
            printf("Student removed.\n");
            return;
        }
    }
    printf("Student not found.\n");
}

void print_student(struct Student student) {
    printf("ID: %d, Name: %s, Score: %d\n", student.id, student.name, student.score);
}

void print_all_students() {
    for (int i = 0; i < num_students; i++) {
        print_student(students[i]);
    }
}

int main() {
    int choice;
    while (1) {
        printf("1. Add student\n");
        printf("2. Remove student\n");
        printf("3. Print all students\n");
        printf("4. Exit\n");
        printf("Please enter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                add_student();
                break;
            case 2:
                remove_student();
                break;
            case 3:
                print_all_students();
                break;
            case 4:
                return 0;
            default:
                printf("Invalid choice.\n");
        }
    }
}
