输入三个数字，从大到小输出

#include <stdio.h>
int main()
{
    int a = 0;
    int b = 0;
    int c = 0;
    scanf("%d%d%d", &a, &b, &c);
    if (a < b)
    {
        int tmp = a;   //将临时变量命名为tmp
        a = b;         //把b赋值给a
        b = tmp;
    }
    if(a<c)
    {
        int tmp = a;
        a = c;
        c = tmp;
    }
    if (b < c)
    {
        int tmp = b;
        b = c;
        c = tmp;
    }
    printf("%d %d %d", a, b, c);
    return 0;
}
