class 里的内容是：
class Ship

private:
int length;
direction orientation;
point origin;
PointCollection points;
PointCollection hits;
public:
Ship(point originPoint,direction orientationDirection,int lengthValue);
Ship(const Ship&);

void shotFiredAtPoint(const point& p);
bool isHitAtPoint(const point& p);
int hitCount() const;
const Ship& operator=(const Ship& s);
};
//然后这里报错!
bool Ship::collidesWith(const Ship* s)const{
s = new Ship[s->length];
}

s = new Ship[s->length];是创建了一个Ship对象数组,这时候会调用Ship的构造函数,对Ship进行初始化,此时调用的是无参的构造函数,但是你的程序中没有这样的够构造函数,所以出错了.
解决办法：
1、在Ship类中,添加无参构造函数.
2、在创建对象数组时,创建有参数的.
