编写一个 C++程序，在其中创建一个含有 5 个元素的 Student 类的对象数组，并 给对象数组成员赋值，然后输出对象数组。输出对象数组时分别使用点（.）运算符和箭 头（->）运算符。

以下是一个简单的示例程序，实现了创建一个包含5个元素的Student类的对象数组，并赋值，最后使用点和箭头运算符输出对象数组的成员：

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

// 定义学生类
typedef struct {
    char name[20];
    int age;
    float score;
} Student;

int main() {
    // 创建包含5个元素的对象数组
    Student students[5];

    // 给对象数组成员赋值
    strcpy(students[0].name, "Tom");
    students[0].age = 18;
    students[0].score = 89.5;

    strcpy(students[1].name, "Jerry");
    students[1].age = 19;
    students[1].score = 91.0;

    strcpy(students[2].name, "Lucy");
    students[2].age = 20;
    students[2].score = 87.5;

    strcpy(students[3].name, "Lily");
    students[3].age = 18;
    students[3].score = 92.0;

    strcpy(students[4].name, "Jim");
    students[4].age = 19;
    students[4].score = 88.5;

    // 使用点运算符输出对象数组的成员
    printf("Using dot operator:\n");
    for (int i = 0; i < 5; i++) {
        printf("Name: %s, Age: %d, Score: %.1f\n", students[i].name, students[i].age, students[i].score);
    }

    // 使用箭头运算符输出对象数组的成员
    printf("Using arrow operator:\n");
    for (int i = 0; i < 5; i++) {
        printf("Name: %s, Age: %d, Score: %.1f\n", (students + i)->name, (students + i)->age, (students + i)->score);
    }

    return 0;
}

输出结果如下：

Using dot operator:
Name: Tom, Age: 18, Score: 89.5
Name: Jerry, Age: 19, Score: 91.0
Name: Lucy, Age: 20, Score: 87.5
Name: Lily, Age: 18, Score: 92.0
Name: Jim, Age: 19, Score: 88.5
Using arrow operator:
Name: Tom, Age: 18, Score: 89.5
Name: Jerry, Age: 19, Score: 91.0
Name: Lucy, Age: 20, Score: 87.5
Name: Lily, Age: 18, Score: 92.0
Name: Jim, Age: 19, Score: 88.5
