如果你有兴趣，请帮我调试一下，错的地方帮我注释，先谢了~！~

有些小错误,我在上面标志了

[iawenll]

name = new char[strlen(className)+1];
//改一
//strlen返回的长度不含'\0'结束符在内，应加1

int main()
{
Base* pBase = new Subclass("test");
//Base::print(*pBase);
//此处，将指针指向了基类，所以下面的输出是随机的
//因为你原本构造的是Subclass类的，进行了截取
printf("name: %s\n", pBase->getName());
printf("new name: %s\n", pBase->copyName());
//Base::print(*pBase);
//改到此处，就可以正常输出了

return 0;
