What's the solution for 'Incomplete type not allowed' ? / structure, c language

Question

This is the structure I used:
typedef struct Date struc_date;
struct Date
{
int dd;
int mm;
int yy;
} ;
struc_date date;

Until here declaration and definition all fine but when I use:

scanf("%d", &date.dd);
printf(" Your date : %d", date.dd);
It gives me an error : incomplete type not allowed.

What's the problem here? Can someone explain what exactly the problem here?
Btw I am using Microsoft visual studio 2017.

Answer 1

ALi Missaoui I don't have vs 2017 with me, but it worked on app in playground for c language as below:

#include <stdio.h>
struct Date
{
int dd;
int mm;
int yy;
} ;

typedef struct Date struc_date;

int main()
{
struc_date date;

scanf("%d", &date.dd);
printf(" Your date : %d", date.dd);
return 0;
}
