剛學SO~問的題目可能會比較淺

希望有大大可以指導我~萬般感謝~!

(我的C++程式為 :Microsoft Visual Studio 6.0)

-----------------------------

#include <iostream.h>
using namespace std;

int main()
{
 int a, b, c;
 cin >> a >> b >> c;
 cout << "請輸入三角形三邊長" << a << "cm" << b << "cm" << c << "cm" << endl;
 float s;
 cin >> a >> b >> c;
 s = ( 1 / 2) * (a + b + c);
 float A;
 A = (s * (s - a) * (s - b) * (s - c) );
 float L;
 L = pow(A , 0.5);
 cout << "三角形面積為" << L << "平方單位" << endl;
 cout << endl << endl << endl;
 return 0;
}
