判断是否能构成三角形并计算面积

这里写代码#include <stdio.h>#include <stdlib.h>#include <math.h>int main(){    int a,b,c,s;    double area;    printf ("input a b c:");    while(1)    {            scanf ("%d%d%d",&a,&b,&c);            if (a+b>c&&b+c>a&&a+c>b)    {        s=(0.5)*(a+b+c);        area=sqrt(s*(s-a)*(s-b)*(s-c));        printf("能构成三角形\n");        printf("%f\n",area);    }     else     printf("不能构成三角形\n");    }     return 0;}这里写代码片```![这里写图片描述](http://img.blog.csdn.net/20171105233657516?watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvVFhfMzgzODE1MTcxNTY=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast)片<div class="se-preview-section-delimiter"></div>
