c - int to structure member is not working -

typedef struct { int row; int col; int max_gray; int **matrix; } pgmdata; void readpgm(const char *file_name, pgmdata *data) { file *pgmfile; char version[3]; int i, j, tmp; int lo, hi; skipcomments(pgmfile); fscanf(pgmfile, "%d", &tmp); printf("d"); data->col=tmp; // error here printf("d"); skipcomments(pgmfile); fscanf(pgmfile, "%d", &tmp); data->row=tmp; skipcomments(pgmfile); fscanf(pgmfile, "%d", &tmp); data->max_gray=tmp; fgetc(pgmfile); }

hello. seek assign int tmp struct data's col can not show when printf

printf("%d",data->col);

instead of -> , used . said not structure. because construction pointer -> can utilize think.

in code write error here. prints first d cant print sec d, programme shuts down. error?

i set & tmp still same.

c struct
