平均分（柬埔寨偶像練習）

我在編碼專案時遇到了一些麻煩，問題如下。

一個特定的才藝比賽有五名評委，每個評委給每個表演者打分，分數在 0 到 10 之間。允許使用分數分數，例如 8.3。表演者的最終分數是通過去掉收到的最高分和最低分，然后取其余三個分數的平均值來確定的。撰寫使用這種方法計算參賽者分數的程式。

我必須使用以下內容，void getJudgeData()、void calcScore()、double findLowest()、double findHighest()

我的代碼如下

#include <iostream>
using namespace std;

double inputValidation(double);
void getJudgeData(double&);
void calcScore(double, double, double, double, double);
double ifLowest(double, double, double, double, double);
double findLowest(double, double, double, double, double);
double ifHighest(double, double, double, double, double);
double findHighest(double, double, double, double, double);

int main()
{
    double score1, score2, score3, score4, score5;

    getJudgeData(score1);
    getJudgeData(score2);
    getJudgeData(score3);
    getJudgeData(score4);
    getJudgeData(score5);

    calcScore(score1, score2, score3, score4, score5);

    return 0;
}

double inputValidation(double num)
{
    while (!(cin >> num) || (num < 0 || num > 10))
    {
        cout << "Incorrect Score parameters" << endl;
        exit(0);
        return 0;
    }
    return num;
}

void getJudgeData(double& num)
{
    cout << "Enter Score: ";
    num = inputValidation(num);
}

void calcScore(double num1, double num2, double num3, double num4, double num5)
{
    double average, lowest = findLowest(num1, num2, num3, num4, num5), highest = findHighest(num1, num2, num3, num4, num5);

    if ((num1 == lowest)||(num5 == highest))
        average = (num2   num3   num4) / 3;
    else if ((num2 == lowest)||(num4 == highest))
        average = (num1   num3   num5) / 3;
    else if ((num3 == lowest)||(num3 == highest))
        average = (num1   num2   num4   num5) / 3;
    else if ((num4 == lowest)||(num2 == highest))
        average = (num1   num3   num5) / 3;
    else if ((num5 == lowest)||(num1 == highest))
        average = (num2   num3   num4) / 3;

    cout << "The average is: ";
    cout << average << endl;
}

double ifLowest(double num1, double num2, double num3, double num4, double num5)
{
    double lowest{};
    if (num1 <= num2)
    {
        if (num1 <= num3)
        {
            if (num1 <= num4)
            {
                if (num1 <= num5)
                {
                    lowest = num1;
                }
            }
        }
    }
    return lowest;
}

double findLowest(double num1, double num2, double num3, double num4, double num5)
{
    double smallest;

    smallest = ifLowest(num1, num2, num3, num4, num5);
    smallest = ifLowest(num2, num3, num4, num5, num1);
    smallest = ifLowest(num3, num4, num5, num1, num2);
    smallest = ifLowest(num4, num5, num1, num2, num3);
    smallest = ifLowest(num5, num1, num2, num3, num4);

    return smallest;
}

double ifHighest(double num1, double num2, double num3, double num4, double num5)
{
    double highest{};
    if (num5 >= num2)
    {
        if (num5 >= num3)
        {
            if (num5 >= num4)
            {
                if (num5 >= num1)
                {
                    highest = num5;
                }
            }
        }
    }
    return highest;
}
double findHighest(double num1, double num2, double num3, double num4, double num5)
{
    double largest;

    largest = ifHighest(num1, num2, num3, num4, num5);
    largest = ifHighest(num2, num3, num4, num5, num1);
    largest = ifHighest(num3, num4, num5, num1, num2);
    largest = ifHighest(num4, num5, num1, num2, num3);
    largest = ifHighest(num5, num1, num2, num3, num4);

    return largest;
}

在 void calcScore 中，平均值給了我一個錯誤，但只有當我嘗試降低最高分時才取平均值

uj5u.com熱心網友回復：

為了解決這個問題，您不需要定義 isLowest() 和 isHighest() 函式。您可以通過比較所有數字直接找到最高和最低數字，而且在您的 calcScore() 函式中，您還沒有涵蓋所有情況。例如，如果 num1 最低，而 num2 最高。這是正確的代碼 -

#include <iostream>
using namespace std;

double inputValidation(double);
void getJudgeData(double &);
void calcScore(double, double, double, double, double);
double findLowest(double, double, double, double, double);
double findHighest(double, double, double, double, double);

int main()
{
  double score1, score2, score3, score4, score5;

  getJudgeData(score1);
  getJudgeData(score2);
  getJudgeData(score3);
  getJudgeData(score4);
  getJudgeData(score5);

  calcScore(score1, score2, score3, score4, score5);

  return 0;
}

double inputValidation(double num)
{
  while (!(cin >> num) || (num < 0 || num > 10))
  {
    cout << "Incorrect Score parameters" << endl;
    exit(0);
    return 0;
  }
  return num;
}

void getJudgeData(double &num)
{
  cout << "Enter Score: ";
  num = inputValidation(num);
}

void calcScore(double num1, double num2, double num3, double num4, double num5)
{
  double average, lowest = findLowest(num1, num2, num3, num4, num5), highest = findHighest(num1, num2, num3, num4, num5);
  average = (num1   num2   num3   num4   num5 - lowest - highest) / 3;
  cout << "The average is: ";
  cout << average << endl;
}

double findLowest(double num1, double num2, double num3, double num4, double num5)
{
  double temp[] = {num1, num2, num3, num4, num5};
  double smallest = num1;
  for (int i = 0; i < 5; i  )
  {
    if (temp[i] < smallest)
    {
      smallest = temp[i];
    }
  }

  return smallest;
}

double findHighest(double num1, double num2, double num3, double num4, double num5)
{
  double temp[] = {num1, num2, num3, num4, num5};
  double largest = num1;
  for (int i = 0; i < 5; i  )
  {
    if (temp[i] > largest)
    {
      largest = temp[i];
    }
  }

  return largest;
}
