Re: Date Alert Reminder

see the ansi time() function, decribed in the C time.h header file.

Here is my code, in C :

C Syntax (Toggle Plain Text)
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
 
/**retrieves the current date.
  * the given parameters are filled with the current time values
  */
void retrieve_time(int* day, int* month, int *year)
{
    time_t t=time(NULL);
    struct tm* timeinfo=localtime(&t);
    *day=timeinfo->tm_mday;
    *month=timeinfo->tm_mon+1;/*junuary->1 december->12*/
    *year=timeinfo->tm_year+1900;
}
 
int main(void)
{
      int day, month, year;
      retrieve_time(&day, &month, &year);
      if(day==31 && month==10 && year==2005)
      {
          printf("happy halloween 2005 !\n");
      }
      return EXIT_SUCCESS;
}
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

/**retrieves the current date.
  * the given parameters are filled with the current time values
  */
void retrieve_time(int* day, int* month, int *year)
{
    time_t t=time(NULL);
    struct tm* timeinfo=localtime(&t);
    *day=timeinfo->tm_mday;
    *month=timeinfo->tm_mon+1;/*junuary->1 december->12*/
    *year=timeinfo->tm_year+1900;
}

int main(void)
{
      int day, month, year;
      retrieve_time(&day, &month, &year);
      if(day==31 && month==10 && year==2005)
      {
          printf("happy halloween 2005 !\n");
      }
      return EXIT_SUCCESS;
}

Re: Date Alert Reminder

Yes, just look at the other members of the tm struct.
