C - Array type has incomplete element type for array of structs

Question

typedef char line_t[MAX_INPUT + 1];

struct {
    line_t line;
    double score;
    int linenumber;
} line_rank;

struct line_rank lines[MAX_LINES + 1];

Produces this : error: array type has incomplete element type which refers to the last line in the code I have provided.

I have looked everywhere and can't seem to find another question relating to structs manipulated in such a way.

The type struct line_rank is incomplete, because it has not be defined anywhere. — user2698605

@pablo1977 I don't understand? The third last line of the code has the previous struct declared as line_rank? — Laefica

No, there you have defined an anonymous struct and a global variable line_rank having this type. — user2698605

@pablo1977 Ahhh, so it's a typedef issue as MikeCAT has answered. Cheers. — Laefica

You may want to add typedef and delete struct.

typedef char line_t[MAX_INPUT + 1];

typedef struct {
    line_t line;
    double score;
    int linenumber;
} line_rank;

line_rank lines[MAX_LINES + 1];
