蓝桥杯算法提高VIP-Quadratic Equation-题解（C语言代码）

解题思路:

注意事项:

参考代码:

#include <stdio.h>

#include <math.h>

int main ()

{

double a,b,c;

scanf("%lf %lf %lf",&a,&b,&c);

double s1,s2;

s1=-b/2/a+sqrt(b*b-4*a*c)/2/a;

s2=-b/2/a-sqrt(b*b-4*a*c)/2/a;

double max=s1>s2?s1:s2;

double min=s2<s1?s2:s1;

printf("%.2lf %.2lf",max,min);

return 0;

}
