已知：a=3.5,b=5.4,c=4.3,编程以求a,b,c为边长的三角形的面积Area=___
提示：Area=根号下s(s-a)(s-b)(s-c) 其中S=a+b+C/2

#include#includevoid main(){ float a=3.5,b=5.4,c=4.5; float s,area;s=a+b+c/2; area=sqrt(s*(s-a)*(s-b)*(s-c));printf("area=%f",area);}...

//通过运行#include #include main() { float a=3.5,b=5.4,c=4.3,area,s;s = a+b+c/2; area = sqrt(s*(s-a)*(s-b)*(s-c));printf("%f\n",area);getch();}...
