【求助】结构体作返回值
#include "math.h"#include "stdio.h"
struct cir_area
{
float l,s;};
struct cir_area c_area(float a,float b,float c)
{
struct cir_area result;
result.l=(a+b+c)/2;
reault.s=sqrt(reault.l*(result.l-a)*(result.l-b)*(result.l-c));
return result;
}
void main()
{
float a,b,c;
struct cir_aera triangle;
printf("输入三角形的3条边长: \n");
scanf("%f,%f,%f",&a,&b,&c);
triangle=c_area(a,b,c);
printf("半周长是: %f\n面积是: %f\n",triangle.l,triangle.s);
}
哪里错了，运行不了，书上例题，照打的
