评委打分案例
1.利用容器
#include <iostream>
using namespace std;
#include<string>
#include<vector>
#include<deque>
#include<algorithm>
class Person
{
public:
Person(string name, int score)
{
this->m_name = name;
this->m_score = score;
}
string m_name;
int m_score;
};
void xuanshou(vector<Person>& v)
{
string m = "ABCDE";
for (int i = 0; i < 5; i++)
{
string name = "选手 ";
name += m[i];
int score = 0;
Person p(name, score);
v.push_back(p);
}
}
void setscore(vector<Person>& v)
{
deque<int>d;
for (vector<Person>::iterator it = v.begin(); it != v.end(); it++)
{
for (int i = 0; i < 10; i++)
{
int score = rand() % 41 + 60;
d.push_back(score);
}
sort(d.begin(), d.end());
d.pop_back();
d.pop_front();
int sum = 0;
for (deque<int>::iterator dit = d.begin(); dit != d.end(); dit++)
{
sum += *dit;
}
int aver = sum / d.size();
it->m_score = aver;
}
}
void showperson(vector<Person>& v)
{
for (vector<Person>::iterator it = v.begin(); it != v.end(); it++)
{
cout << "姓名： " << it->m_name << "平均分： " << it->m_score << endl;
}
}
int main()
{
srand((unsigned int)time(NULL));//随机时间种子
vector<Person> v;
xuanshou(v);
setscore(v);
showperson(v);
system("pause");
}
2.利用STL容器
#include <iostream>
#include <string>
#include<vector>
#include<deque>
#include <algorithm>
using namespace std;
class Player
{
public:
string name;
int score;
Player(){}
Player(string n,int s):name(n),score(s){}
};
bool mtcompare(Player& p1, Player& p2)
{
return (p1.score > p2.score);
}
void printmy(int n)
{
cout << n << " ";
}
//创建选手信息
void Setplay(vector<Player>& v)
{
string nameseed = "ABCDE";
for (int i = 0; i < 5; i++)
{
string n = "选手";
n += nameseed[i];
Player p;
p.name = n;
p.score = 0;
v.push_back(p);
}
}
//打分
void Setscore(vector<Player>& v)
{
for (vector<Player>::iterator it = v.begin(); it != v.end(); it++)
{
deque<int>d;
for(int i=0;i<10;i++)
{
(*it).score = rand() % 41 + 60;
d.push_back((*it).score);
}
/*for_each(d.begin(), d.end(), printmy);
cout << endl;*/
//排序一下
sort(d.begin(), d.end());
//删除最高分和最低分
d.pop_front();
d.pop_back();
int total = 0;
for (deque<int>::iterator dit = d.begin(); dit != d.end(); dit++)
{
total += (*dit);
}
int ave = total / d.size();
(*it).score = ave;
}
}
//打印排序输出
void get(vector<Player>& v)
{
sort(v.begin(), v.end(), mtcompare);
for (vector<Player>::iterator it = v.begin(); it != v.end(); it++)
{
cout << (*it).name << " " << "分数为：" << (*it).score << endl;
}
}
int main()
{
vector<Player>v;
Setplay(v);
Setscore(v);
get(v);
}

{
public:
