C-数组类型的结构数组的元素类型不完整

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.

Answer 1

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];
