若有以下程序段,则使用错误的选项是(). struct student { int num; int age; }; struct student stu[3]={{1001,20},{1002,19},{1004,20}}; void main(); { struct student *p; p=stu; … }
A.p++
B.(*p).num
C.(p++)->num
D.p=&stu.age
有下列语句: struct Birthday{public int year; public int month; public int day;}; struct Student{ int no; string name; int age; public Birthday bir; }; …… Student Stu; 如果要把Stu的出生年份赋值为1988,正确的语句是()A、 Stu.bir.year=1988;B、 Stu.year=1988;C、 Stu. Birthday.year=1988;D、 Student. Birthday.year=1988;

数据结构里,struct student { char name[20]; char sex[10]; int age; int score; }; 定义结构体后,定义变量、数组赋值正确的是()。A、struct student s={"张三","男",18,100};B、struct student stu[3]={{"张三","男",18,100},{"李四","男",19,90},{"王五","男",23,97}};C、struct student s={"李四";"女";18;100};D、struct student stu[3]={{"张三",18,"男",100},{"李四",19,"男",90},{"王五",23,"男",97}};
有以下说明语句:struct Student{int num;double score;};Student stu[3]={{1001,80},{1002,75},{1003,91}},*p=stu;则下面引用形式错误的是()A、p->numB、(p++).numC、(p++)->numD、(*p).num
单选题若有以下说明和语句: struct student{ int age; int num; }std, *p; p=&std; 则下面对该结构体变量std中成员age的引用方式错误的是()。A std.ageB *p.ageC (*p).ageD p->age
单选题有以下说明语句:struct Student{int num;double score;};Student stu[3]={{1001,80},{1002,75},{1003,91}},*p=stu;则下面引用形式错误的是()A p->numB (p++).numC (p++)->numD (*p).num
单选题有以下程序:#include struct STU{ int num; float TotalScore;};void f(struct STU p){ struct STU s[2] = {{20044,550}, {20045,537}}; p.num = s[1].num; p.TotalScore = s[1].TotalScore;}main(){ struct STU s[2] = {{20041,703}, {20042,580}}; f(s[0]); printf(%d %3.0f, s[0].num, s[0].TotalScore);}程序运行后的输出结果是( )。A 20045 537B 20044 550C 20042 580D 20041 703
单选题有以下函数:#include struct stu{ int num; char name[10]; int age;};void fun(struct stu *p){ printf(%s, p->name);}main(){ struct stu x[3] = {{01,Zhang,20}, {02,Wang,19}, {03,Zhao,18}}; fun(x+2);}程序运行后的输出结果是( )。A ZhangB ZhaoC WangD 19
