单链表插入
class A {
struct B {
C *m_function;
struct B *m_next;
};
static struct B *head;
public:
static void insert(C *f);
};
A::B *A::head;
void A::insert(C *f)
{
struct B *old=head;
head = new struct B;
head->C = f;
head->m_next = old;
}
C::C()
{
A::insert(this);
}
有段错误
[解决办法]
不知道你想要什么,你的代码也不全,我自己加了一下。自己看吧,只是编译可过,
是不是你想要的不知道。
class C;
class A
{
struct B
{
C *m_function;
struct B *m_next;
};
static struct B *head;
public:
static void insert(C *f);
};
class C
{
public:
C()
{
A::insert(this);
}
};
A::B *A::head;
void A::insert(C *f)
{
struct B *old=head;
head = new struct B;
head->m_function = f;
head->m_next = old;
}
