各位大哥大姐帮个忙啊！
这个程序在ＶＣ＋＋上运行结果上正确的．但是在我们学校的交题系统确是编译错误：
Compile Error
54583\Main.cc: In function `int main()':
54583\Main.cc:68: error: no matching function for call to `Circle::Circle(int&, int&, Circle&)'
54583\Main.cc:32: note: candidates are: Circle::Circle(const Circle&)
54583\Main.cc:35: note: Circle::Circle(int, int, int)
Sample Input
R 10 20 10 20
C 20 10 10
R 3 3 4 5
E
Sample Output
Rectangle 1: Area=200 Perimeter=60 point=(10,20)
Circle 2: Area=314.159 Perimeter=62.8318 center point=(20,10)
Rectangle 3: Area=20 Perimeter=18 point=(3,3)
我的源代码如下：

};

//Rectangle r;
