error with code

Im getting an error when compiling that says "assignments makes integer from pointer without a cast". For all three assignment statements.

Code:

---

if (res == 0){
        day = current_day;
        mon = current_month;
        year = current_year;

---

current_day
Current_month and
current_year are all in another file, that i have #included.

Code:

---

if (res == 0)
{
    day = *current_day;
    mon = *current_month;
    year = *current_year;
    ....
}

---

Without the '*' you're assigning the addresses at which the pointers current_day, current_month and current_year are pointing to the integer variables day, mon and year. With '*' you're assigning the data that is stored at the address that the pointer is pointing at.

even with the pointers *. i still get the same error. Ill put all of the code so you can see it all.

Code:

#include <stdio.h>
#include <time.h>
#include <sys/time.h>

#include "date.c"

Now im getting a totally wrong date being outputted. current_year is saying 1970! something is still not working right but i cant figure out what it is. Also when i try to print out the month name i get an exception: status_access_violation.

Code:

---

         
  int do_day ( char *cmd ) {
         
      int day;   
      int month;
      int year;
      int res;
      char mon;
      res = sscanf( cmd, "%*c %d %d %d", &day, &month, &year );
      if (res == 0){
        day = current_day();
        mon = current_month();
        year = current_year();
              printf("%d %d \n", day, year);
              return 0;
      }

---

Thanx salem, it fixed the problem. I assumed everything to be correct in that date.c file because the teacher set it up, but apparently not :). Um my next task is:
The program reads and executes multiple commands, each consisting of a single line. It terminates at end of file on input or when it reads a blank line.

Do you think that it means that the program reads a line of input, produces some output, and then waits for another line of input, and if its a blank line the program terminates?

I cant really understand what this is asking. I dont want any code for this, just an opinion of what you think the task is asking.
Cheers guys.

If there is one thing I have learned, it is to NEVER trust your tutors! They tell me all sorts of garbage, and hardly any of the programs they have written for me work!!;)

what im trying to do now is make it so that the person can enter either a number for the month, or the name of the month itself.

Like:d 23 November 2002

Am i on the right track here?
