下列关于《中华人民共和国政府采购法》、《中华人民共和国招标投标法》的说法正确的是()。

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; 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;

A、struct student { char num[5]; int score; }; student stu1,stu2;

B、struct student stu1,stu2; struct student { char num[5]; int score; };

C、struct student { char num[5]; int score=96; }; struct student stu1,stu2;

D、struct student { char num[5]; int score; }; struct student stu1,stu2;

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;

struct student { long num； int score； struct student*next； }； struct student*insert(struct student*head，struct student * p) { struct student*p1，*p2，*p0； p1=head； (1)： if(p1==NULL) { head=p0； (2)； } else { if((3)) { p2=p1； p1=p1->next； } if(p0->num==pl->num) { (4)； (5)； n=n+1： } else { printf(“＼n％ld not been found!＼n”，num)； } } return head； }

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.

A. struct student{ int num; char name[20];}s

B. struct { int num; char name[20]; }S

C. struct student{ int num; char name[20]; }; struct student s

D. struct student{ int num; char name[20]; }; student s

运行下列程序，输出结果是（）. struct student { int num; struct student *next; }; int main() { struct student a[3]={1,&a[1],2,&a[2],3,&a[0]},*p; p=&a[1]; printf("%d%d\n ",p->num,p->next->num); return 0; }
