输入三角形三边长,求三角形面积.#include“math.h”main(){floata,b,c,s,area;scanf(“%f,%f,%f”,&a,&b,&c);s=1.0/2*(a+b+c);

先给个好评!再答：

//使用海伦公式#include/*ForIO*/#include/*Forsqrt()*/intmain(void){doublea,b,c,p,s;printf("请输入a,b和c：");scan

C编程求助编写一个基于对象的程序：输入半径,计算圆的周长和面积并输出实现#include

clearinput"请输入圆的半径："torl=2*pi()*rs=pi()*r*r?"周长是：",l?"面积是：",s

m=2a+2b;应该改成m=2*a+2*b;程序中2a,2b是不允许的,没有意义的.
