举一反三
- 若有以下定义语句,则以下错误的引用是( )。 struct student {int num,age;}; struct student stu[3]={{101,20},{102,19},{103,18}},*p=stu;
- 若有以下定义语句:struct student{ int num,age;};struct student stu[3]={{101,20},{102,19},{103,18}},*p=stu;则以下错误的引用是( ) A: (p++)->num B: p++ C: (*p).num D: p=&stu.age
- 若有以下定义语句,则以下错误的引用是( )。struct student{ int num,age;};struct student stu[3]={{101,20},{102,19},{103,18}},*p=stu; A: (p++)->num B: p++ C: (*p).num D: p=&stu.age
- 有以下说明和定义语句 structstudent {int age; char num[8];}; structstudentstu[3]={{20,"200401"},{21,"200402"},{19,"200403"}}; structstudent *p=stu; 以下选项中引用结构体变量成员的表达式错误的是______。
- 若有下列语句,则以下引用方式不合法的是( )。 struct student { int num; int age; }; struct student stu[3]={{101,20}, {102,19}, {103,20}}, *p=stu;

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;

有以下说明和定义语句 , 以下选项中引用结构体变量成员的表达式错误的是( ) struct student { int age; char num[8];}; struct student stu[3]={{20,"200401"},{21,"200402"},{19,"200403"}}; struct student *p=stu;

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;

若能使程序运行后的输出结果如下: 201501 则空白处填写的表达式或语句应该是 #include structstudent { intage; charnum[8]; }; intmain() { structstudentstu[3]={{20,"201501"},{21,"201502"},{19,"201503"}}; structstudent*p=stu; ____________________ return0; }

若有以下说明和定义语句,则下面引用形式中不正确的是 ( )。 struct student { int age; int num; }; struct student stu[3]={{1001,20},{1002,19},{1003,21}}; struct student *p; p=stu;
