成员变量：姓名、年龄、性别、学号、数学成绩、语文成绩、英语成绩； 方法：构造函数、析构函数、获取总分数的方法、获取平均分数的方法。 请编写程序计算Tom同学的总分和平均分,假设Tom同学今年18岁, 男生, 学号是20220001, 语数外的成绩分别是90, 95, 80。

以下是一个可能的实现：

#include <iostream>
#include <string>

using namespace std;

class Student {
public:
    string name;
    int age;
    char gender;
    string id;
    int mathScore;
    int chineseScore;
    int englishScore;

    Student(string n, int a, char g, string i, int m, int c, int e) {
        name = n;
        age = a;
        gender = g;
        id = i;
        mathScore = m;
        chineseScore = c;
        englishScore = e;
    }

    ~Student() {}

    int getTotalScore() {
        return mathScore + chineseScore + englishScore;
    }

    double getAverageScore() {
        return (mathScore + chineseScore + englishScore) / 3.0;
    }
};

int main() {
    Student tom("Tom", 18, 'M', "20220001", 90, 95, 80);
    cout << "Tom's total score is: " << tom.getTotalScore() << endl;
    cout << "Tom's average score is: " << tom.getAverageScore() << endl;
    return 0;
}

输出结果：

Tom's total score is: 265
Tom's average score is: 88.3333
