设有以下说明structstudent{intnum;charsex;intage;}a1,a2;则下面的用法中不正确的是().

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;

中国大学MOOC: 有以下说明和定义语句，下面各输入语句中错误的是#include<stdio.h>intmain(){structstudent{intage;charsex;charname[8];};structstudentstd;structstudent*p=&std;.......return0;}

若有以下定义和语句: struct student {int num ;int age;}; struct student stu[3]={{l001,20},{1002,19},{1003,2l}}; main() {struct student *p;p=stu; ... } 则下列引用中不正确的是
