已知有以下由字符串组成的二维数组 char name[5][20]={"baidu","alibaba","tencent","jd","bytedance"};用选择排序法将字符串按照名字长度的降序排序

以下是使用选择排序法将字符串按照名字长度的降序排序的C++代码：

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

int main()
{
    char name[5][20] = {"baidu", "alibaba", "tencent", "jd", "bytedance"};
    int len[5];
    for (int i = 0; i < 5; i++)
    {
        len[i] = strlen(name[i]);
    }
    for (int i = 0; i < 4; i++)
    {
        int max_len = len[i];
        int max_index = i;        for (int j = i + 1; j < 5; j++)
        {
            if (len[j] > max_len)
            {
                max_len = len[j];
                max_index = j;
            }
        }
        if (max_index != i)
        {
            swap(len[i], len[max_index]);
            swap(name[i], name[max_index]);
        }
    }
    for (int i = 0; i < 5; i++)
    {
        cout << name[i] << endl;
    }
    return 0;
}
