如何在C中将结构的内容保存到文件中？

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

FILE *file = fopen("data.txt", "w");

Student student;
student.id = 1;
strcpy(student.name, "John");
student.score = 90.5;

fprintf(file, "%d %s %.2f\n", student.id, student.name, student.score);

fclose(file);

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

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

int main() {
    FILE *file = fopen("data.txt", "w");
    if (file == NULL) {
        printf("Failed to open file.\n");
        return 1;
    }

    Student student;
    student.id = 1;
    strcpy(student.name, "John");
    student.score = 90.5;

    fprintf(file, "%d %s %.2f\n", student.id, student.name, student.score);

    fclose(file);

    return 0;
}
