为什么我的结构变量不包含此成员？

Question

我写了下面的代码：

#include <stdio.h> 
#include <stdlib.h> 


typedef struct 
{ 
    int month; 
    int day; 
    int hour; 
    int minutes; 
}primaries_date; 

typedef struct 
{ 
    int all_members; 
    char *country; 
    primaries_date date; 
}usa_primaries; 

typedef struct node *ptr; 

typedef struct node 
{ 
    usa_primaries up; 
    ptr next; 
}Node; 



void add(ptr usa_primaries *hptr, int all_members, char *con, int month,  int day, int hour, int minutes) 
{ 
    ptr p; 
    ptr q; 
    ptr t; 
    t = malloc(sizeof(Node)); 
    if(!t) 
    { 
     printf("Cannot build list"); 
     exit(0); 
    } 

    t->all_members = members; 
    t->county = con; 
    t->date->month = d->month; 
    t->date->day = d->day; 
    t->date->hour = d->hour; 

    while((p1)) 
    { 
     if(p->date->month >= month || p->date->day >= day ||  p->date->hour >= hour || p->date->minutes >= minutes) 
     { 
      q = p; 
      p = p->next; 
     } 
    } 

    if(p == *hptr) 
    { 
     *hptr = t; /*Resetting head. Assigning to the head t*/ 
     t->next = p; 
    } 
    else 
    { 
     q->next = t; 
     t->next = p; 
    } 
} 


int main() 
{ 
    ptr h; 
    int month, day, hour, minutes; 
    int all_memebers; /*Declaration of all_members*/ 
    char *county; 
    char member; 
    printf("Please enter the day"); 
    scanf("%d",&day); 
    printf("Please enter the month"); 
    scanf("%d",&month); 
    printf("Please enter the hour"); 
    scanf("%d",&hour); 
    printf("Please enter the minutes"); 
    scanf("%d",&minutes); 
    printf("Is this an all-member candidate? Y/N"); 
    scanf("%c",&member); 
    if(member == 'Y') 
    all_members = 1; 
    else 
    all_members = 0; 
    printf("Please enter the country"); 
    scanf("%s",&county); 

    add(&h,all_members,country,month,day,hour,minutes); 

    return 0; 
} 

我得到这个错误：

usa.c: In function ���add���: 
usa.c:42:6: error: ���struct node��� has no member named  ���all_members��� 
t->all_members = members; 
^

我真的不明白，为什么这个错误发生，因为all_members在结构usa_primaries宣布，结构节点，其中包含usa_primaries结构。

为什么显示此错误，我该如何解决？

Answer 1

Node没有all_members。它有一个usa_primaries和那有all_members。因此：

t->up.all_members
