ASCII码排序

 思路：利用ascll表比较大小

代码：

#include<iostream>
using namespace std;

int main()
{
    char a, b, c, t;
    while (cin >> a >> b >> c)
    {
        if (a > c)
        {
            t = a;
            a = c;
            c = t;
        }
        if (b > c)
        {
            t = b;
            b = c;
            c = t;
        }
        if (a > b)
        {
            t = a;
            a = b;
            b = t;
        }
        printf("%c %c %c
", a, b, c);
    }

    system("pause");
    return 0;
}
