Which is true according to the passage？A．The shop was on the Second Road.B．The boy was 18

若有以下定义的语句

struct student

{ int age;

int num; };

struct student stu[3]={{1001,20},{1002,19},{1003,21}};

main()

{ struct student *p;

p=stu;

… }

则以下不正确的引用是

A．(p++)->num

B．p++

C．(*p).num

D．P=&stu.age.

若有以下定义的语句： struct student { int age； int num；}； struct student stu[3]={{1001，20}，{1002，19}，{1003，21}}； main() { struct student *p； p=stu； …} 则以下不正确的引用是()。

A．(p++)-＞num

B．p++

C．(*p).num

D．P=&stu.age．

若有以下定义的语句 struct student {int age； int num；}； struct student stu[3]={{1001，20}，{1002，19}，{1003，21}}； main() {stmct student *p； p=stu； …} 则以下不正确的引用是

A．(p++)-＞num

B．p++

C．(*p).num

D．P=&stu.age．

若有以下语句，则下面表达式的值为1002的是( )。

struct student

{int age;

int num;

};

struct student stu[3]={{1001,20},{1002,19},{1003,21}};

struct student *p;

p=stu;

A．(p++)-＞num B．(p++)-＞age C．(*p).num D．(*++p).age

A．p=stu;

B．*p=*stu;

C．*p=&stu;

D．p=&stu;

若有以下说明和语句

struct student

{int age;

int num;

}std, *p;

p=＆std;

则以下对结构体变量std中成员age的引用方式不正确的是( )。

A．std.age B．p-＞age C．(*p).age D．*p.age

A、#define STUDENT struct student STUDENT{ int num; float age; }std1;

B、struct student{ int num; float age; }std1;

C、struct{ int num; float age; }std1;

D、struct{ int num; float age; }student; struct student std1;

A、struct student {int num; char name[10];int age;};stu;

B、struct {int num; char name[10];int age;}student; struct student stu;

C、struct student {int num; char name[10];int age;}stu;

D、struct student {int num; char name[10]; int age;}; student stu;

A、struct student { int num; int age; } stud1;

B、struct { int num; int age; } stud1;

C、typedef struct student { int num; int age; }STUDENT; STUDENT stud1;

D、struct { int num; int age; }; struct student stud1;

有以下说明和定义语句

struct student

{ int age; char num[8];};

struct student stu[3]={{20,"200401"},{21,"200402"},{10\9,"200403"}};

struct student *p=stu;

以下选项中引用结构体变量成员的表达式错误的是

A．(p++)->num

B．p->num

C．(*p).num

D．stu[3].age
