【C++】STL案例1-评委打分

0.前言

在这里插入图片描述

1.系统自动生成的评委评分代码：

#include <iostream>
using namespace std;
#include <deque>
#include <vector>
#include <algorithm>
#include <string>//选手类
class Player
{
public:Player(string name, float score){m_Name = name;m_Score = score;}string m_Name; //姓名float m_Score; //平均分
};//创建选手
void createPlayer(vector<Player>& player)
{string Sname = "ABCDE";for (int i = 0; i < 5; i++){string name = "选手";name += Sname[i];float score = 0;Player p(name, score); //创建选手player.push_back(p);  //将创建的选手Player对象 放入到容器中}
}//给选手打分
void setScore(vector<Player>& player)
{srand((unsigned int)time(NULL));  //设置种子，确保每次运行生成不同的随机数for (vector<Player>::iterator it = player.begin(); it != player.end(); it++){deque<int>d; //创建deque容器，将十个评委的评分放入容器中for (int i = 0; i < 10; i++){float score = rand() % 41 + 60;  //评分 60~100 利用随机数d.push_back(score);}sort(d.begin(), d.end()); //将评分升序排序//去除最高分和最低分d.pop_back();d.pop_front();float sum = 0; //总分变量for (deque<int>::iterator dit = d.begin(); dit != d.end(); dit++){sum += *dit;  //将十个评分累加}float avg = sum / d.size();  //均分it->m_Score = avg;}
}//显示选手分数
void showScore(vector<Player>& player)
{for (vector<Player>::iterator it = player.begin(); it != player.end(); it++){cout << it->m_Name << "\t\t" << "平均分为：" << it->m_Score << endl;}cout << "选手评分结束！" << endl;
}int main() 
{vector<Player>player;createPlayer(player); //创建五名选手setScore(player); //给选手评分showScore(player); //显示选手分数//**************************************system("pause");return 0;
}

2.用户手动输入评委评分代码：

#include <iostream>
using namespace std;
#include <deque>
#include <vector>
#include <algorithm>
#include <string>//选手类
class Player
{
public:Player(string name, float score){m_Name = name;m_Score = score;}string m_Name; //姓名float m_Score; //平均分
};//创建选手
void createPlayer(vector<Player>& player)
{string Sname = "ABCDE";for (int i = 0; i < 5; i++){string name = "选手";name += Sname[i];float score = 0;Player p(name, score); //创建选手player.push_back(p);  //将创建的选手Player对象 放入到容器中}
}//给选手打分
void setScore(vector<Player>& player)
{//srand((unsigned int)time(NULL));  //设置种子，确保每次运行生成不同的随机数cout << "请在场的十位评委们给选手们打分：" << endl;for (vector<Player>::iterator it = player.begin(); it != player.end(); it++){cout << it->m_Name << " 的十个分数分别为：" << endl;deque<int>d; //创建deque容器，将十个评委的评分放入容器中for (int i = 0; i < 10; i++){//float score = rand() % 41 + 60;  //评分 60~100 利用随机数//手动输入评分float score;cin >> score; d.push_back(score); //将分数插入deque容器中}sort(d.begin(), d.end()); //将评分升序排序//去除最高分和最低分d.pop_back();d.pop_front();float sum = 0; //总分变量for (deque<int>::iterator dit = d.begin(); dit != d.end(); dit++){sum += *dit;  //将十个评分累加}float avg = sum / d.size();  //均分it->m_Score = avg;}
}//显示选手分数
void showScore(vector<Player>& player)
{cout << "各选手的得分情况如下：" << endl;for (vector<Player>::iterator it = player.begin(); it != player.end(); it++){cout << it->m_Name << "\t\t" << "平均分为：" << it->m_Score << endl;}cout << "选手评分结束！" << endl;
}int main() 
{vector<Player>player;createPlayer(player); //创建五名选手setScore(player); //给选手评分showScore(player); //显示选手分数//**************************************system("pause");return 0;
