编写以下程序：以文本“写”方式打开文本student1.txt文件，调用函数outputToFile，将这5个同学的信息存入student1.txt 文本文件，关闭该文件； 注：函数outputToFile输入参数为student_info、5和已打开的文件指针fp。 ⑤以文本“读”方式打开文本 student1.txt 文件，调用函数inputFromFile，将这5个同学的信息读入并存放到结构体数组student_info1中，关闭该文件；

以下是该程序的实现：

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

struct student {
    char name[20];
    int age;
    float score;
};

void outputToFile(struct student student_info[], int n, FILE *fp) {
    int i;
    for (i = 0; i < n; i++) {
        fprintf(fp, "%s %d %.1f\n", student_info[i].name, student_info[i].age, student_info[i].score);
    }
}

void inputFromFile(struct student student_info[], int n, FILE *fp) {
    int i;
    for (i = 0; i < n; i++) {
        fscanf(fp, "%s %d %f", student_info[i].name, &student_info[i].age, &student_info[i].score);
    }
}

int main() {
    FILE *fp;
    struct student student_info[5] = {
        {"Tom", 18, 90.5},
        {"Jerry", 19, 85.0},
        {"Bob", 20, 92.5},
        {"Alice", 21, 88.0},
        {"John", 22, 95.5}
    };
    struct student student_info1[5];
    int i;

    fp = fopen("student1.txt", "w");
    if (fp == NULL) {
        printf("Cannot open file.\n");
        exit(1);
    }
    outputToFile(student_info, 5, fp);
    fclose(fp);

    fp = fopen("student1.txt", "r");
    if (fp == NULL) {
        printf("Cannot open file.\n");
        exit(1);
    }
    inputFromFile(student_info1, 5, fp);
    fclose(fp);

    for (i = 0; i < 5; i++) {
        printf("%s %d %.1f\n", student_info1[i].name, student_info1[i].age, student_info1[i].score);
    }

    return 0;
}

程序的输出结果为：

Tom 18 90.5
Jerry 19 85.0
Bob 20 92.5
Alice 21 88.0
John 22 95.5
