Question

编程，某歌手大赛有10位选手10位评委要求评委给10位选手打分去掉一个最低分去掉一个最高分求出平均分

Answer 1

1、首先，定义一个整型变量num，保存评委的人数。

2、接着，定义5个实型变量，保存所打的分数、最低分、最高分、总分和平均分。

3、初始化最低分和最高分，最低分为1000分，最高分为0分。

4、接着，设置总分分数，值为0。

5、输入评委的人数，保存在变量num中。

6、然后，提示输入评委的打分。

7、执行for循环语句，条件为i小于等于num。

8、运行程序，输入各评委的打分后，就会计算出节目的最后得分。

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
bool MinScore(double v1, double v2)
{
    return (v1 < v2);
}
int main(int argc, char *argv[])
{
    vector<double> dvec;
    double score;
    cout << "Please input 10 scores: " << endl;
    while (cin >> score && dvec.size() != 10)
    {
        dvec.push_back(score);
    }
    stable_sort(dvec.begin(), dvec.end(), MinScore);
    for (int i = 0; i < 10; ++i)
    {
        cout << dvec[i] << " ";
    }
    cout << endl;
    vector<double>::iterator it = dvec.begin()+1;
    while (it != dvec.end()-1)
    {
        score += *it++;
    }
    score /= (dvec.size()-2);
    cout << "Score = " << score << endl;
    return 0;
}

include <stdio.h>
include <math.h>
double average(int i,flot max,flot min);
void main ()
flote a[10][10],double b[10];
int i,j;
flote max,min;
for(i=0;i<10;i++)
for(j=0;j<10;j++)
scanf("f%",a);//评分输入
for(i=0;i<10;i++)
for(j=0;j<10;j++)
｛
max=(a[i][j]>a[i][j+1]);
min=(a[i][j]<a[i][j+1]);
}
for(i=0;i<=10;i++)
{
b[i]=average(i);
printf("%.2f/n",b[i]);
}
double average(int i,flote max,flote min)
{
double m=0;
int j;
for(j=0;j<=10;j++)
m+=a[i][j];
m=(m-max-min)/8
return m;
}

我这个是C++的代码 里面含有标准库。
#include<iostream>
#include<vector>
#include<deque>
#include<string>
#include<algorithm>
#include<ctime>
using namespace std;

class Person
{
public:
Person(){};
Person(string name, double score)
{
this->m_Name = name;
this->m_Score = score;
}

string m_Name;
double m_Score; //平均分

};

void creatPerson(vector<Person>&v,int n)
{

int score = 0;
for (int i = 0; i < n; ++i)
{
string name1 = to_string(i+1); //int类型转化为string类型
string name2 = "号选手";
name1 += name2;
Person p(name1, score);
v.push_back(p);
}

}

void printVector(vector<Person>&v)
{
for (vector<Person>::iterator it = v.begin(); it != v.end(); ++it)
{
cout << it->m_Name << "最终平均分数为：" << it->m_Score << endl;

}

}

void printVector2(vector<Person>&v)
{
for (vector<Person>::iterator it = v.begin(); it != v.end(); ++it)
{
cout << it->m_Name << " ";
}
cout << endl;
}

void setVector(vector<Person>&v,int m)
{
for (vector<Person>::iterator it = v.begin(); it != v.end(); ++it)
{
deque<int>d;
cout << "已为" << it->m_Name <<"打了"<<m <<"次分：" << endl;
for (int i = 0; i < m; ++i)
{
int score = rand() % 41 + 60;
d.push_back(score);
}

for (deque<int>::iterator dit = d.begin(); dit != d.end(); ++dit)
{
cout << *dit << " ";
}
cout << endl;

sort(d.begin(), d.end());

d.pop_front();
d.pop_back();

/*for (deque<int>::iterator dit = d.begin(); dit != d.end(); ++dit)
{
cout << *dit << " ";
}
cout << endl;*/

int sum = 0;
for (deque<int>::iterator dit = d.begin(); dit != d.end(); ++dit)
{
sum += *dit;
}
//cout << "sum=" << sum << "数量" << d.size() << endl;

double avg = sum*1.0 / d.size();

it->m_Score = avg;

}
cout << endl;
}

void sortScore(vector<Person>&v)
{
vector<Person>::iterator it = v.begin();

Person t;
for (unsigned int i = 0; i < v.size(); ++i)
{
for (unsigned int j = 0; j < v.size() - i - 1; ++j)
{
if (it[j].m_Score>it[j + 1].m_Score) //比较分数
{
t = it[j]; //更换整体
it[j] = it[j + 1];
it[j + 1] = t;
}
}
}

}

int main(void)
{
cout << "软件说明：" << endl;
