#include<stdio.h>
#include <math.h>
int main(void)
{
    double a=0, b=0, c=0;
    double s=0, area=0;
    printf("请输入三角型三边:");
    scanf("%lf%lf%lf", &a, &b, &c);
    if (a + b > c && a + c > b && b + c > a)
    {
        s = (a + b + c) / 2;
        area = sqrt(s * (s-a)*(s - b)*(s - c));
        printf("三角形面积=%lf\n", area);
    }
    else
    {
        printf("error\n");
    }
    return 0;
