程序代码：

#include"iostream"
using namespace std;
void sort(char *_temp, int length);
int main()
{
    char arr[3][3];
    int i;
    for (i = 0; i < 3; i++)
    {
        cin >> arr[i][0] >> arr[i][1] >> arr[i][2];
        sort(arr[i], 3);
    }
    for (i = 0; i < 3; i++)
    {
        cout << arr[i][0] <<" "<< arr[i][1] <<" "<< arr[i][2]<<endl;
    }
}
void sort(char *_temp, int length)
{
    int i, j;
    char cup;
    for (i = 1; i < length;i++)
    for (j = 1; j <= length - i; j++)
    if (_temp[j - 1]>_temp[j])
    {
        cup = _temp[j - 1];
        _temp[j - 1] = _temp[j];
        _temp[j] = cup;
    }
}
