已知有typedef struct student STU;下面和struct student s1;等效的是?()
A: STU s1;
B: student STU s1;
C: struct STU s1;
D: typedef STU s1;
A: STU s1;
B: student STU s1;
C: struct STU s1;
D: typedef STU s1;
举一反三
- 对以下定义,能输出字符串"Mary"的语句是( )。struct student { char name[20]; int age; }; struct student stu[100]={"John",16,"Paul",17,"Mary",18 }; A: printf("%s",stu[2].name); B: printf("%s",stu[1].name); C: printf("%s",stu[2]); D: printf("%s",stu[1]);
- 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;
- 若有定义:struct student{ int age; int num;};struct student stu,*p;则以下正确的赋值语句是()。 A: p=stu; B: *p=*stu; C: *p=&stu; D: p=&stu;
- 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;
