Question

这是我需要解决的程序：

编写一个程序，要求用户输入10个不同的人（Person 1, Person 2, ..., Person 10）吃早餐的煎饼数量。
一旦输入数据，程序必须分析数据并输出哪个人吃早餐最煎饼。

是否有人可以编写返回最大值索引的代码（我将其标记为“h”）

#include "iostream"

using namespace std;

int main()
{

    int x[11];
    int y;
    int h;
    for (int i = 1; i <= 10; i++)
    {
        cin >> i[x];
        cout << "Person: " << i << " has eaten " << i[x] << " pancakes" << endl
        y = x[0];
        h = x[0];


        for (int j = 1; j <= 10; j++)
        {
            if (x[j] > y)
            {
                y = x[j];
            }
        }
    }
    cout << "The most pancakes are eaten by Person " << h << " with " << y << endl;
    system("pause");
    return 0;
}

Answer 1

未经测试，应该有效：

#include <iostream>

using namespace std;

int main()
{

    int x[11];
    int ans, ansmax = 0;
    for (int i = 1; i <= 10; i++)
    {
        cin >> x[i]; // You had wrong variable here
        cout << "Person: " << i << " has eaten " << x[i] << " pancakes" << endl
        if(x[i] > ansmax)
        {
            ansmax = x[i];
            ans = i;
        }
    }
    cout << "The most pancakes are eaten by Person " << ans << " with " << ansmax << endl;
    system("pause");
    return 0;
}

Answer 2

我的五美分

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
    const int N = 10;
    int person[N];

    // Entering initial data
    for ( int i = 0; i < N; i++ )
    {
        cout << "Enter number of pancakes eaten by person " << i + 1 << ": ";
        cin >> person[i];
    }

    //  Finding the index (favorite) of the person who has eaten the most pancakes.
    int favorite = 0;

    for ( int i = 1; i < N; i++ )
    {
        if ( person[favorite] < person[i] ) favorite = i;
    }

    // Now all is ready to show the result
    cout << "\nThe most pancakes are eaten by Person " << favorite + 1 
         << " with " << person[favorite] << endl;

    system( "pause" );

    return 0;
}

Answer 3

#include <algorithm>

int index = std::max_element(x, x + 11) - x;

返回最大值的索引
