c++程序如何改。关于类的

#include

class CPoint
{
public:
unsigned x,
unsigned y;
bool IsInCircle(CCircle Circle)
{
return (((x-Circle->Center.x)(x-Circle->Center.x)
+(y-Circle->Center.y)*(y-Circle->Center.y))<=Circle->Radius*Circle->Radius);
}
};

class CCircle
{
public:
unsigned Radius;
CPoint Center;
};

void main()
{

}

class CPoint里unsigned x;写成了unsigned x,
