有关C语言问题 求解
若有以下定义和语句：
struct student
{
int num, age;
};
struct student stu[3] = {{1001, 20}, {1002, 19}, {1003, 21}};
struct student *p = stu;
则以下错误的引用是 _____。选择一个答案
A. (p++)->num
B. (*p).num
C. p = &stu.age
D. p++

为什么选择C呢？希望给出详解？ 这个题中涉及哪些知识点？

struct student **p = &studentt; 这句话怎么解释?为什么是两个**
不好意思,多写了一个t,student是一个结构体,不明白为什么指针能指向一个结构体?结构体还没有实例化,那儿来的地址?
struct student **p = &student; 这句话怎么解释?为什么是两个**

C# color是一个结构名?
① Color 与我自己定义的一个结构：
public struct student
{}
中的student的地位一样吗?也就是说Color是一个结构名而不是一个实例?
②
Color.
Color newcolor =Color.
③ 创建一个实例时：
Color A与Color A=new Color()有什么不同?

c语言 大神求指导

若有以下说明，则下面哪个叙述是正确的（已知short占2个字节,float占4个字节）。

1. struct
2. {
3. short a;
4. float b;
5. } v1;

1. union
2. {
3. short a;
4. float b;
5. } v2;

得分/总分

• A.

  执行sizeof(v1)获得的结果是6个字节，只能对结构体变量v1中的第一个成员进行初始化。

• B.

  执行sizeof(v2)获得的结果是8个字节，只能对共用体变量v2中的第一个成员进行初始化

• C.

  执行sizeof(v1)获得的结果是8个字节，对结构体变量v1中的任何一个成员都可以进行初始化。

• D.

  执行sizeof(v2)获得的结果是6个字节，只能对共用体变量v2中的第一个成员进行初始化。

.owner是什么意思
static struct file_operations dev_fops = {
.owner = THIS_MODULE,
.ioctl = sbc2440_leds_ioctl,
};我知道owner,ioctl都是file_operations的成员,不明白前面要加个“.”的作用
不是要问这个单词什么意思

struct定义中在成员后面加冒号“：
typedef unsigned char u_char;
struct frame_control {
u_char fc_subtype :4;
u_char fc_type :2;
u_char fc_protocol_version :2;
u_char fc_order :1;
u_char fc_wep :1;
u_char fc_more_data :1;
u_char fc_pwr_mgt :1;
u_char fc_retry :1;
u_char fc_more_frag :1;
u_char fc_from_ds :1;
u_char fc_to_ds :1;
};
里面成员定义中加:

(36)没有定义
struct complex
{ int real,unreal ;} datal={1,8},data2; 则以下赋值语句中的错误的是
A）data2=data1; B）data2=(2,6); C）data2.real1=data1.real; D）data2.real=data1.unreal;

14. 设有以下说明语句 struct student { int x ; float y; ch
14. 设有以下说明语句
struct student
{ int x ; float y; char z ;} p,*example=&p;
则下面正确的是 B 。
A) struct.x B) example->z C) student->x D) example.z

求翻一篇(小)英语文章!很快的
Honeybees cannot live alone.Their body-structure and instincts equip them for life in a colony or community,where they have a complex social organization and the various duties are divided among the individuals according-to physical fitness and age.An individual worker bee cannot reproduce itself.While it may continue to live if forcibly isolated from its mates,it fails to care for itself adequately,an soon dies.Most insects have the abliity to hibernate in winter,but the honeybee seems to have lost this.Since at low temperatures the bee will die,it must have the ability to make its own environment,so far as temperature is concerned.This makes a colony necessary to the bees in winter,so that they may collectively warm each other.Efficiency,if not necessity,demands that the work of the colony be divided,and such a division of labor tends to enhance the need to maintain thecolony.The physical structure of the honeybee is further suited for the defense of the fact that it is left behind in the victim.With the loss of the sting,however,the bee dies.This kind of defensive weaponis not of service to the individual,but to the community.
