C++vector针对排序操作练习

目的：

定义5个学生，包含名字和分数，对成员进行从大到小排序，并输出

#include <iostream>
#include <cstring>
#include <vector>
#include <random>
#include <ctime>
#include <algorithm>
using namespace std;
//定义Student类，设置名字和分数属性
class Student{
public:
    Student(int score,string name){
        this->name = name;
        this->score = score;
    }
public:
    int score;
    string name;
};
//设置类成员
void SetStudent(vector<Student> &s){
    string name[5] ={"aa","bb","cc","dd","ee"};
    Student a(0,"");
    srand(time(0));
    for(int i =0;i<5;i++){
        a.name = name[i];
        a.score = 60+random()%40;
        s.push_back(a);
    }
}
//定义针对Student类的排序规则函数
bool My_count(Student &v1,Student &v2){
    return v1.score>v2.score;
}
//设置分数,对分数进行排名
void SetScore(vector<Student> &s){
    sort(s.begin(),s.end(),My_count);//sort()支持随机存储容器，传入规则时，不带()
}
//利用迭代器对成员进行输出
void CoutScore(vector<Student> &s){
    for(vector<Student>::iterator it = s.begin();it != s.end();it++){
        cout <<"Student :"<<(*it).name <<"  "<<"Score :"<<(*it).score<<endl;
    }
}

int main() {
    vector<Student> s;
    SetStudent(s);
    SetScore(s);
    CoutScore(s);
    return 0;
}
