Question

当我尝试将我的函数用于最大值时，它会一直返回错误的值。

#include <iostream>
#include <iomanip>
using namespace std;

int largest(int[], int);

main()
{
const int size = 3;
int a[size];

for (int i = 0; i < size; i++)
 {  cout << "Enter an array element ";
     cin >> a[i];   
}


 int large = largest(a,size);
 cout << "Largest is " << largest;

return 0;   
}

int largest (int a[], int size )
{
    int largest;  largest = a[0];


    for (int i = 1; i < size; i++)
    {
        if(a[i] > largest)
        {
        largest = a[i];
        return largest; }
    }

}

Answer 1

返回语句应该在for循环之后才能找到最大值。

int largest (int a[], int size )
{
    int largest;  largest = a[0];
    for (int i = 1; i < size; i++)
    {
        if(a[i] > largest)
            largest = a[i];
    }
    return largest;
}

你有两个问题：a）你第一次回来是＆gt; a [0]，b）您在<RelativePanel> <Button Name="Button1" Content="Button 1" RelativePanel.AlignHorizontalCenterWithPanel="True" RelativePanel.AlignVerticalCenterWithPanel="True"/> <Button Name="Button2" Content="Button 2" RelativePanel.AlignHorizontalCenterWithPanel="True" RelativePanel.AlignVerticalCenterWithPanel="True" RelativePanel.Below="Button1"/> <Button Name="Button3" Content="Button 3" RelativePanel.AlignHorizontalCenterWithPanel="True" RelativePanel.AlignVerticalCenterWithPanel="True" RelativePanel.Below="Button2"/> </RelativePanel>中捕获返回值，但是您打印large，这将打印该函数的地址。

largest

具有最大阵列功能的程序
