C语言代码使用结构体表示一个学生的信息，包括学号，姓名，性别，盛日，班级，每门课的成绩，并编写程序完成学生信息的录入，查询，信息列表的功能

以下是使用C语言的结构体表示学生信息的代码：

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

#define MAX_NAME_LEN 20
#define MAX_CLASS_LEN 10
#define MAX_SUBJECTS 5
#define MAX_STUDENTS 100

struct student {
    int id;
    char name[MAX_NAME_LEN];
    char gender;
    char birthday[11];
    char class[MAX_CLASS_LEN];
    int scores[MAX_SUBJECTS];
};

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

void add_student() {
    struct student s;
    printf("Enter student ID: ");
    scanf("%d", &s.id);
    printf("Enter student name: ");
    scanf("%s", s.name);
    printf("Enter student gender (M/F): ");
    scanf(" %c", &s.gender);
    printf("Enter student birthday (YYYY-MM-DD): ");
    scanf("%s", s.birthday);
    printf("Enter student class: ");
    scanf("%s", s.class);
    printf("Enter student scores (separated by spaces): ");
    for (int i = 0; i < MAX_SUBJECTS; i++) {
        scanf("%d", &s.scores[i]);
    }
    students[num_students++] = s;
    printf("Student added successfully!\n");
}

void list_students() {
    printf("ID\tName\tGender\tBirthday\tClass\tMath\tEnglish\tPhysics\tChemistry\tBiology\n");
    for (int i = 0; i < num_students; i++) {
        printf("%d\t%s\t%c\t%s\t%s\t", students[i].id, students[i].name, students[i].gender, students[i].birthday, students[i].class);
        for (int j = 0; j < MAX_SUBJECTS; j++) {
            printf("%d\t", students[i].scores[j]);
        }
        printf("\n");
    }
}

void search_student() {
    int id;
    printf("Enter student ID to search: ");
    scanf("%d", &id);
    for (int i = 0; i < num_students; i++) {
        if (students[i].id == id) {
            printf("ID\tName\tGender\tBirthday\tClass\tMath\tEnglish\tPhysics\tChemistry\tBiology\n");
            printf("%d\t%s\t%c\t%s\t%s\t", students[i].id, students[i].name, students[i].gender, students[i].birthday, students[i].class);
            for (int j = 0; j < MAX_SUBJECTS; j++) {
                printf("%d\t", students[i].scores[j]);
            }
            printf("\n");
            return;
        }
    }
    printf("Student not found!\n");
}

int main() {
    int choice;
    while (1) {
        printf("\n1. Add student\n2. List students\n3. Search student\n4. Exit\n\nEnter your choice: ");
        scanf("%d", &choice);
        switch (choice) {
            case 1:
                add_student();
                break;
            case 2:
                list_students();
                break;
            case 3:
                search_student();
                break;
            case 4:
                exit(0);
            default:
                printf("Invalid choice!\n");
                break;
        }
    }
    return 0;
}

这个程序可以实现录入、查询和显示学生信息的功能。你可以根据自己的需求进行修改。
