用C语言 将三个数从大到小排序

#include <stdio.h>int main(){double a = 0.0, b = 0.0, c = 0.0;double t = 0.0;printf("输入三个数：");scanf("%lf %lf %lf", &a, &b, &c);if (a-b <= 1e-7){t = a;a = b;b = t;     /*a是a,b中较大的*/}if (a-c <= 1e-7){t = a;a = c;c = t;     /*a是a,b,c中较大的*/}if (b-c <= 1e-7){t = b;b = c;c = t;     /*b是b,c中较大的*/}printf("从大到小的顺序是：%lf  %lf  %lf\n", a, b, c);return 0;}
