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
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
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;
- 对结构体类型变量定义不正确的是（ ）。 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;
- 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}
