flag used with `%s' printf format.

[DocHaydn]

Hello,
I'm a learner. Compiler: MinGW Developer Studio, O/S:Win'98SE.

The program is a mail manager, taken from my "C"
book:"C by Example". On compilation, I'm getting the
warning:"`'flag used with `%s' printf format."

I've tried changing the function's return type, but no go.
How do I resolve this problem?
I'll only post the offending part of the program.

Thank you.

/*Global structure of name and address.*/

struct mail_struct
{
char name[25];
char address[25];
char city[20];
char province[20];
char zipcode[7]; /* Extra NULL character.*/
char code[10]; /*For additional expansion.*/

};

/*Global file pointer.*/

   printf("\nName : %-25s \n", item.name);
   fflush(stdout);

   fflush(stdout);
   printf("City : %- 20s \tProvince: %- 20s ZIPcode: %- 6s \n",
           item.city, item.province, item.zipcode);
   fflush(stdout);

   return 0;      
}

Perhaps it's all those spaces between the - and the 20

Eg, try

printf("City : %-20s \tProvince: %-20s ZIPcode: %-6s \n"
