Question

以下代码旨在要求用户指定他们想要输入的整数数，然后查找并显示它们之间的最大值和最小值。但是，它没有编译，可能是因为我初始化minInt和maxInt变量的方式，但我不确定。请帮忙！提前谢谢！

#include <iostream>
using namespace std;
int main()

{
        int inNum, inInt, minInt, maxInt, i;

        minInt = INT_MAX;
        maxInt = INT_MIN;
        cout << "How many numbers would you like to enter?" << endl;
        cin >> inNum;
        cout << "Please enter " << inNum << " integers." << endl;
        for(i = 0 ; i < inNum; i++)
        {
                cin >> inInt >> endl;
                if(inInt > maxInt)
                {
                        maxInt = inInt;
                }
                if(inInt < minInt)
                {
                        minInt = inInt;
                }
        }
        cout << "min: " << minInt << endl;
        cout << "max: " << maxInt << endl;
        return 0;
}

Answer 1

这是你的问题：

cin >> inInt >> endl;

您不需要在此endl。

cin >> inInt;

Answer 2

我发现了2个错误：

<climits>，其中INT_MAX和INT_MIN已定义
cin不支持endl

所以代码应该是如此：

#include <iostream>
#include <climits>

using namespace std;
int main()
{
    int inNum, inInt, minInt, maxInt, i;

    minInt = INT_MAX;
    maxInt = INT_MIN;
    cout << "How many numbers would you like to enter?" << endl;
    cin >> inNum;
    cout << "Please enter " << inNum << " integers." << endl;
    for(i = 0 ; i < inNum; i++)
    {
            //Error 3: cin >> inInt >> endl; cin does not support endl
            cin >> inInt;
            if(inInt > maxInt)
            {
                    maxInt = inInt;
            }
            if(inInt < minInt)
            {
                    minInt = inInt;
            }
    }
    cout << "min: " << minInt << endl;
    cout << "max: " << maxInt << endl;
    return 0;
}

使用C ++中的for循环从用户输入中查找最大和最小整数？
