struct inside struct [英] Struct inside struct

问题描述

我必须创建一个人，每个人都应该有一个冰箱。这是最好的做法吗？如果是这样我做错了什么？提前感谢。

  typedef struct {
 int age; 
 struct FRIDGE冰箱; 
} PERSON; 
 
 typedef struct {
 int number; 
} FRIDGE; 
 
 FRIDGE fr; 
 fr.number = 1; 
 
个人
 me.name = 1; 
 me.fridge = fr; 
  

这给我以下错误：

< >

错误：字段冰箱不完整类型

解决方案

struct FRIDGE 是不同于 FRIDGE 的东西。

需要在其他结构中使用类型 FRIDGE 。

  typedef struct {
 int age; 
 FRIDGE冰箱; 
} PERSON; 
  

或将您的冰箱定义为 struct FRIDGE

  struct FRIDGE {
 int number; 
}; 
  

此外，结构可能必须在使用之前定义/ p>

I must create a Person and each Person should have a Fridge. Is this the best way of doing it? If so what am I doing wrong? Thanks in advance.

typedef struct {
 int age;
 struct FRIDGE fridge;
} PERSON;

typedef struct {
 int number;
} FRIDGE;

FRIDGE fr;
fr.number=1;

PERSON me;
me.name=1;
me.fridge = fr;

This gives me the following error:

error: field ‘fridge’ has incomplete type

解决方案

struct FRIDGE is something different than FRIDGE.

You need to either use type FRIDGE in your other structure.

typedef struct {
 int age;
 FRIDGE fridge;
} PERSON;

or define your fridge as struct FRIDGE

struct FRIDGE {
 int number;
};

Also, the structure may have to be defined before you use it (e.g. above the person).
