Typedef struct指向另一个typedef结构的指针

Question

我对此代码有一些问题：

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];

为什么Product *ptr给我一个错误？

Answer 1

您可以尝试替换代码吗

typedef struct Product {

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

用

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

你可以这样做：

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];
