Typedef结构体指向另一个typedef结构体的指针

Question

I have some problems with this code:

typedef struct Product {

    char product_code[5];
    int sells;
    int sells_quantity;
}p[3];

typedef struct Seller {
    char seller_code[5];
    Product *ptr;
}seller[5];

Why does it give me an error for Product *ptr ?

Answer 1

Could you try replace your code

typedef struct Product {

    char product_code[5];
    int sells;
    int sells_quantity;
}p[3];

With

typedef struct Product {

    char product_code[5];
    int sells;
    int sells_quantity;
} Product;               // from here the structure type Product is recognized by the compiler. 

Answer 2

You can do this :

typedef struct Product {

char product_code[5];
int sells;
int sells_quantity;
}p[3],Product;

typedef struct Seller {
  char seller_code[5];
  Product *ptr;
}seller[5];
