c++ - 我如何找出数组中的哪个元素具有最高值？

Question

#include <iostream>

using namespace std;

int main()
{
    int personPancake[10];
    int small, big;

    for (int c = 0; c < 10; c++)
    {
        cout << "Enter how many pancakes person " << c + 1 << " ate: ";
        cin >> personPancake[c];
    }

    big = small = personPancake[0];

    for (int c = 0; c < 10; c++)
    {
        if (personPancake[c] > big)
        {
            big = personPancake[c];
        }

        if (personPancake[c] < small)
        {
            small = personPancake[c];
        }
    }

    cout << "Biggest: " << big << endl;
    cout << "Smallest: " << small << endl << endl;
}

这是我在 atm 上的代码，我已经计算出最小和最大的数字，如您所见。我需要帮助找出拥有最大和最小值的元素的索引。

您可以设置另外两个变量来保存当前最小和最大索引。所以在你的 if 语句中......

int biggestIndex, smallestIndex;

if (personPancake[c] > big)
    {
        biggestIndex = c;
        big = personPancake[c];
    }

    if (personPancake[c] < small)
    {
        smallestIndex = c;
        small = personPancake[c];
    }
