有如下程序： Dim a(3，3)As Integer For m ＝ 1 To 3 For n ＝ 1 To 3 a(m，n)＝(m-1)*3＋n Next n Next m For m ＝ 2 To 3 For n ＝ 1 To 2 Print a(n，m)； Next n Next m 运行后，输出结果是(　　)。

下列程序段的执行结果为（）。 Dim M(2) For i=l To 2 M(i... M(k); Next j Next i

下列语句中可以完成建立2结点的单向链表的功能的选项是()。 A: head→next=new;new→next=head; B: new→next=head;head=new; C: new→next=head;head=new;new→next=Null; D: head→next=Null;head→next=new;new→next=NULL;

下列程序代码的运行结果为（ ）。 Private Sub Command1_Click() For m = 1 To 10 Step 2 a = 10 For n = 1 To 20 Step 2 a = a + 2 Next n Next m Print a End Sub

如下程序段： int c[]={1, 7, 12}; int *k; k=c; printf('next k is %d',*++k); 其输出应为： A: next k is 2 B: next k is 12 C: next k is 7 D: next k is 1

以下程序运行后的输出结果是 ________ struct NODE { int num; struct NODE *next; } main() { struct NODE s[3], *p, *q, *r; int sum=0; s[0].num=1; s[1].num=2; s[2].num=3; s[0].next=s+1; s[1].next=s+2; s[2].next=s; p=s; q=p->next; r=q->next; sum+=q->next->num; sum+=r->next->next->num; printf("%d", sum); }
