[Dev-C++] What's up with scanf and struct's

[<jor...@wa...>]

I'm a newbie. Does any body know what's wrong in the next simple =
program. It's my first time i define an struct, and the problem seems to =
be in the scanf instruction , because if i redefine  "int num" to "char =
num[2]" and use gets() everything goes ok.

#include <stdio.h>
#include <conio.h>
#define MaxEnt 5

struct agenda
 {
  char nombre[25];
  char direcc[25];
  int num;
  char tlf[9];
 } listin[MaxEnt];

main()
{
      int i, n=3D2;

    for(i=3D0;i<MaxEnt;i++)
      {
         printf("Introduzca Nombre:");
         gets(listin[i].nombre);
         printf("Introduzca direccion:");
         gets(listin[i].direcc);
         printf("Introduzca numero:");
         scanf("%i",&listin[i].num);
         printf("Introduzca telefono:");
         gets(listin[i].tlf);
     }
 for(i=3D0;i<n;i++)
     printf("%s %s %s =
%s",listin[i].nombre,listin[i].direcc,listin[i].num,listin[i].tlf);
}
