struct student **p = &studentt; 这句话怎么解释?为什... struct student **p = &studentt; 这句话怎么解释?为什么是两个** struct student **p = &student; 这句话怎么解释?为什么是两个** struct student*fun(struck student *a)怎么解释啊,struct fun(struck struct student{int num,int score}stu; struct student *p;stu A.若有以下说明和语句：struct stu { int no; char *name; }student,*p=&st struct student{int num;char name[20];}stu1;stu1.name="Li Min void input(struct student stu[]);//函数声明 ? 这句话怎么解释? struct st{int x;int*y;}*p;inta[]={1,2},b[]={3,4};struct st c struct S { int i; int * p;}; main () {S s ; int *p =&s.i ; p while(*p&&*p==‘*’) 这句话怎么理解啊
