A:
B: define STUDENT struct studentSTUDENT{char name;int num;}std;
C: struct student{char name;int num;}stu;
D:
E: define struct student{char name;int num;}STD;STD stu;
F: struct{char name;int num;}student;struct student stu;
举一反三
- 以下结构体的定义语句中，正确的是______。? struct student {int num; char name[10];int age;}stu;|struct {int num; char name[10];int age;}student; struct student stu;|struct student {int num; char name[10]; int age;}; student stu;|struct student {int num; char name[10];int age;};stu;
- 以下变量定义，错误的是： 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
- 一下选项中，定义结构体变量错误的是（ ） A: struct student {int num; char name[30];<br> }wangming; B: struct {int num; char name[30];<br> }wangming; C: struct student {int num; char name[30];<br> }; struct student wangming; D: struct student {int num; char name[30];<br> }; student wangming;
- 下列结构体的定义正确的是（ ）。 A: student { int num; char name[10]; char sex; }; B: struct student { int num; char name[10]; char sex; } C: struct student { int num; char name[10]; char sex; }; D: struct student { int num char name[10] char sex };
- 下列选项中不能够定义一个结构体类型变量stu的是 。 A: struct student { int num; int age; } stu; B: struct student { int num; int age; }; student stu; C: struct {int num; int age; } stu; D: struct student {int num; int age; }; struct student stu;

以下各项用于定义结构体类型，并定义结构体变量，其中正确的是________。 A: struct student { char num[5]; int score; }; student stu1,stu2; B: struct student{ char num[5]; int score;};struct student stu1 stu2; 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;

下面定义结构变量的语句中错误的是。 未知类型：{'options': ['struct student{ int num; char name[20]; } s;', 'struct { int num; char name[20]; } s;', 'struct student{ int num; char name[20]; }; struct student s；', 'struct student{ int num; char name[20]; }; student s;'], 'type': 102}

以下对结构体类型的变量定义中不正确的是 。 A: B: define STUD struct student STUD {long num; char name[20]; char sex; float score;}; STUD stud1,stud2; C: struct student {long num; char name[20]; char sex; float score; }stud1,stud2; D: struct {long num; char name[20]; char sex; float score; } stud1,stud2; E: struct {long num; char name[20]; char sex; float score; }student;struct student stud1,stud2;

有以下程序段，输出结果为（）。 #include<stdio.h> struct student {int num; char name[20]; float score; }; main() {struct student stu[5]; printf("%d",sizeof(stu)); }
- 4
struct student { int num; char sex; char name[20]; float score; } st ; 其中num是结构体 ________
