从键盘输入三角形的三边长为a,b,c,按下面公式计算并输出三角形的面积。程序代码如下,但程序运行后输出结果不正确,请找出有问题的语句。 #include <stdio.h> #include <math.h> int main() { float a, b, c; float s, area; printf("Input a,b,c:"); scanf("%f,%f,%f",&a,&b,&c); if (a+b>c && b+c>a && a+c>b) { s = 1/2 * (a + b + c); area = sqrt(s * (s - a) * (s - b) * (s - c)); printf("area=%.2f\n", area); } else { printf("It is not a triangle\n"); } return 0; }
A、第11行: s = 1/2 * (a + b + c);
B、第9行: if (a+b>c && b+c>a && a+c>b)
C、第12行: area = sqrt(s * (s - a) * (s - b) * (s - c));
D、第8行: scanf("%f,%f,%f",&a,&b,&c);
A、**0****2**
B、**0**
C、**0****1****2**
D、有语法错误
