（1）输入两个学生的学号、姓名和成绩，输出成绩较高学生的学号、姓名和成绩. （2）用指针方式实现上面的程序。指针

（1）这是一个简单的编程任务，可以使用结构体或者自定义的对象来存储学生信息，并通过比较分数来找出最高分的学生。以下是使用C++语言的一个示例：

#include <iostream>
using namespace std;

struct Student {
    int id;
    string name;
    int score;
};

void find_highest_score(Student *students, int num_students) {
    Student highest_student = students[0];
    for (int i = 1; i < num_students; i++) {
        if (students[i].score > highest_student.score) {
            highest_student = students[i];
        }
    }
    cout << "学号: " << highest_student.id << ", 姓名: " << highest_student.name << ", 成绩: " << highest_student.score << endl;
}

int main() {
    Student students[] = { {1, "小明", 95}, {2, "小红", 98} };
    int num_students = sizeof(students) / sizeof(students[0]);
    find_highest_score(students, num_students);
    return 0;
}

（2）如果要用指针来实现同样的功能，你可以创建一个指向`Student`类型的指针数组，并遍历这个数组找到最高分的学生。这里是一个指针版本的例子：

#include <iostream>
using namespace std;

struct Student {
    int id;
    string name;
    int score;
};

void find_highest_score(Student *students, int num_students) {
    Student *highest_student = &students[0];
    for (int i = 1; i < num_students; i++) {
        if (students[i].score > highest_student->score) {
            highest_student = &students[i];
        }
    }
    cout << "学号: " << highest_student->id << ", 姓名: " << highest_student->name << ", 成绩: " << highest_student->score << endl;
}

int main() {
    Student *students = new Student[2] {{1, "小明", 95}, {2, "小红", 98}};
    int num_students = 2; // 数组大小
    find_highest_score(students, num_students);
    delete[] students; // 释放内存
    return 0;
}
