若STUDENTstudent1,student2;(student1,student2为结构体变量)为正确定义,那么在此之前应做()定义。
A: struct{charname[20];intnum;}STUDENT;
B: structSTUDENT{charname[20];intnum;};
C: typedefstruct{charname[20];intnum;}STUDENT;
D: typedefstructSTUDENT{charname[20];intnum;};
A: struct{charname[20];intnum;}STUDENT;
B: structSTUDENT{charname[20];intnum;};
C: typedefstruct{charname[20];intnum;}STUDENT;
D: typedefstructSTUDENT{charname[20];intnum;};
举一反三
- 对结构体类型变量定义不正确的是() A: #defineSTUDENTstructstrdentSTRDENT{charname;intnum;}std; B: structstudent{charname;intnum;}stu; C: struct{charname;intnum;}std; D: struct{charname;intnum;}student;structstudentstu;
- 以下定义结构体变量的语句中错误的是()。 A: struct{intnum;charname[20];}s; B: structstudent{intnum;charname[20];}s; C: structstudent{intnum;charname[20];};students; D: structstudent{intnum;charname[20];};structstudents;
- 以下结构体的定义语句中,正确的是() A: structstudent{intnum;charname[10];intage;};stu; B: struct{intnum;charname[10];intage;}student;structstudentstu; C: structstudent{intnum;charname[10];intage;}stu; D: structstudent{intnum;charname[10];intage;};studentstu;
- 若定义结构体类型变量student,以下各项对结构体变量成员引用错误的是()。structstud_type{intnum;charname[10];intage;floatscore;}student;
- 下列对结构类型变量的定义中不正确的是() A: struct{longintnum;charname[20];charsex;charaddr[20];}student;structstudentstd1; B: #defineSTUDENT structstudentSTUDENT{longintnum;charname[20];charsex;charaddr[20];}std1; C: struct{longintnum;charname[20];charsex;charaddr[20];}std1; D: struct student{longintnum;charname[20];charsex;charaddr[20];}std1;
