已知带头结点的链栈top, 则该链栈为空的条件是( )
A: top==NULL
B: top->next= =NULL
C: top->next->next= =NULL
D: top->next= =top
A: top==NULL
B: top->next= =NULL
C: top->next->next= =NULL
D: top->next= =top

举一反三
- 1、已知带头结点的链栈top, 则该链栈不空时, 出栈操作的语句是( ) A: top->next=top->next->next; *x=top->next->data; B: top->next=top->next->next; *x=top->next->data; C: *x=top ->data;p=top;top =p->next;free(p); D: *x=top ->data;p=top;top =p->next;free(p);
- 已知带头结点的链栈top, 则该链栈不空时, 出栈操作的语句是( ) A: top->next=top->next->next; *x=top->next->data; B: *x=top->next->data; top->next=top->next->next; free(top->next); C: *x=top ->data;p=top;top =p->next;free(p); D: *x=top->next->data;p=top->next;top->next=p->next;free(p);
- 已知带头结点的链栈top,则该链栈不空时,出栈操作的语句是____ A: top->next=top->next->next;<br/>*x=top->next->data; B: *x=top->next->data;<br/>p=top->next; top->next=p->next; free(p); C: *x=top->next->data;<br/>top->next=top->next->next; free(top->next); D: *x=top<br/>->data; p=top; top =p->next; free(p);
- 假定一个链栈的栈顶指针用top表示,该链栈为空的条件为( )。 A: top!=NULL B: top=top->next C: top==NULL D: top!=top->next
- 已知带头结点的链栈top, 则元素x对应的新结点s进栈操作的语句是() A: s->next=top->next;top->next=s; B: top->next=s; s->next=top->next; C: s->next=top;top =s; D: top =s; s->next=top;
