以下各项用于定义结构体类型，并定义结构体变量，正确的是（）.
A: structstudent{charnum[5];intscore;};studentstu1,stu2;
B: structstudentstu1,stu2;structstudent{charnum[5];intscore;};
C: structstudent{charnum[5];intscore=96;};structstudentstu1,stu2;
D: structstudent{charnum[5];intscore;};structstudentstu1,stu2;
A: structstudent{charnum[5];intscore;};studentstu1,stu2;
B: structstudentstu1,stu2;structstudent{charnum[5];intscore;};
C: structstudent{charnum[5];intscore=96;};structstudentstu1,stu2;
D: structstudent{charnum[5];intscore;};structstudentstu1,stu2;
举一反三
- 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；
- 已知有结构定义和变量声明如下：structstudent{charname[20];intscore;structstudent*h;}stu,*p;int*q;以下选项中有语法错误的是（）。
- 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; }
- 有以下定义语句:structstudent{intnum;charname[9];}则不能正确定义结构体数组并赋初始值的是 A: structstudentstu[]={{1,"zhangsan"},{2,"lisi"}}; B: structstudentstu[2]={1,"zhangsan",2,"lisi"}; C: structstudentstu[2]={{1,"zhangsan"},{2,"lisi"}}; D: structstu[]={{1,"zhangsan"},{2,"lisi"}};
- 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______。
