请问，我是不是应该释放对象，如果是该怎么释放？谢谢！

class Vehicle
{
public:
	virtual void function()
       {
		......
	}
};
class Car : public Vehicle
{
public:
	void function()
       {
		......
	}
};
class Bike : public Vehicle
{
public:
	void function()
       {
		......
	}
};
int main()
{
	Vehicle* v1 = new Vehicle; //<------应该释放吗？
	Vehicle* v2 = new Car; //<------应该释放吗？
	Vehicle* v3 = new Bike; //<------应该释放吗？
	v1->function();
	v2->function();
	v3->function();
}

直接delete掉v1,v2,v3

[lingyin55]

要释放，加上
delete v1;
delete v2;
delete v3;

基类虚析构函数？

[Eric_Jo]

应该释放啊，
调用Delete就可以了啊。

[/Quote]

delete v1;
delete v2;
delete v3;
还用再加上
v1 = NULL;
v2 = NULL;
v3 = NULL;
吗？

[lingyin55]

嗯，加上好点，虽然不加不会错，但是不加的话重新使用v1好像还是可以的。
所以加上吧。:)

动态申请的内存都要自己释放

[NirvanaVirus]

顶6楼的朋友～

delete v1;
delete v2;
delete v3;
v1 = NULL;
v2 = NULL;
v3 = NULL;

自己释放动态堆空间应该养成这样的好习惯，哪怕是每一次练习也要加上。多少惨痛的经验教训就毁在没有这一步上～

[机智的呆呆]

绝大多数情况下，new/delete malloc/free应该是成对出现的。

[xlttap]

delete v3;
v3 = 0;
delete v2;
v2 = 0;
delete v1;
v1 = 0;

[Walf_ghoul]

delete v1;
delete v2;
delete v3;
v1 = NULL;
v2 = NULL;
v3 = NULL;
