C++ 数组中的最小数字不显示

Question

#include <iostream>

using namespace std;

int main()
{  
    double sixty = 0.0;
    double fiftyfive = 0.0;
    double height[10];
    double tallest = 0.0;
    double shortest = 0.0;
    double average = 0.0;
    double total = 0.0;

    for (int x = 0; x < 10; x = x + 1)
    {
        height[x] = 0.0;
    }

    cout << "Please enter the heights of ten students. "<< endl;
    for (int x = 0; x < 10; x = x + 1)
    {
        cout << "Enter height of a student: ";
        cin >> height[x];
    }

    for (int x = 0; x < 10; x = x + 1)
    {
        if (height[x] > 60)
        {
           sixty = sixty + 1;
          }
    }
    for (int x = 0; x < 10; x = x + 1)
    {
        if (height[x] < 55)
        {
           fiftyfive = fiftyfive + 1;
        }
    }
    cout << "The number of students over 60 inches in height: " << sixty << endl;
    cout << "The number of students under 55 inches in height: " << fiftyfive << endl;

    for (int x = 0; x < 10; x = x + 1)
    {
        if (height[x] > tallest)
        {
                      tallest = height[x];
        }
    }
    cout << "The tallest student is: " << tallest << endl;

    for (int x = 0; x < 10; x = x + 1)
    {
        if (height[x] < shortest)
        {
                      shortest = height[x];
        }
    }
    cout << "The shortest student is: " << shortest << endl;

    for (int x = 0; x < 10; x = x + 1)
    {
        total = total + height[x];
    }
    average = total / 10;
    cout << "The average student height is: " << average << endl;   



    system("pause"); 
    return 0;
}

在上面，我需要吐出60in以上学生人数，55in以上学生人数，平均高度，最高高度，最矮高度。

除最短高度外，一切正常。我为该部分代码返回零输出。

这是一个简单的代码，所以我想这是一个我忽略的简单问题。感谢任何输入。

Answer 1

    if (height[x] < shortest)
    {
                  shortest = height[x];
    }

如果最矮为零，则永远不会有比这更小的学生(除非你有来自外部领域的负高度的学生；))。您需要使用 height[0];
初始化最短同样在这种情况下，您可以从 1 开始迭代学生

shortest = height[0];
for (int x = 1; x < 10; x = x + 1)
{
    if (height[x] > tallest)
    {
                  tallest = height[x];
    }
}
