c语言学生管理系统数据结构设计

以下是一个简单的C语言学生管理系统的数据结构设计示例：

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

#define MAX_STUDENTS 100

typedef struct {
    int studentID;
    char name[50];
    char gender[10];
    int age;
    char birthdate[20];
    char address[100];
    char phone[20];
    char email[50];
} Student;

typedef struct {
    Student students[MAX_STUDENTS];
    int count;
} StudentDatabase;

void initializeDatabase(StudentDatabase *database) {
    database->count = 0;
}

void addStudent(StudentDatabase *database, Student student) {
    if (database->count < MAX_STUDENTS) {
        database->students[database->count] = student;
        database->count++;
        printf("Student added successfully.\n");
    } else {
        printf("Database is full. Cannot add more students.\n");
    }
}

void displayStudents(StudentDatabase database) {
    printf("Student List:\n");
    for (int i = 0; i < database.count; i++) {
        printf("Student ID: %d\n", database.students[i].studentID);
        printf("Name: %s\n", database.students[i].name);
        printf("Gender: %s\n", database.students[i].gender);
        printf("Age: %d\n", database.students[i].age);
        printf("Birthdate: %s\n", database.students[i].birthdate);
        printf("Address: %s\n", database.students[i].address);
        printf("Phone: %s\n", database.students[i].phone);
        printf("Email: %s\n", database.students[i].email);
        printf("--\n");
    }
}

int main() {
    StudentDatabase database;
    initializeDatabase(&database);

    // 添加学生
    Student student1 = {1, "John Doe", "Male", 20, "2000-01-01", "123 Main St", "123-456-7890", "john@example.com"};
    addStudent(&database, student1);

    Student student2 = {2, "Jane Smith", "Female", 22, "1998-05-10", "456 Elm St", "987-654-3210", "jane@example.com"};
    addStudent(&database, student2);

    // 显示学生列表
    displayStudents(database);

    return 0;
}
