Thread: Problem with comparison

Code:

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

char ime[4] = "Thu";
int main ( void )
{
  time_t now;
  struct tm *tm_now;
  char buff[BUFSIZ];

  now = time ( NULL );
  tm_now = localtime ( &now );

  strftime ( buff, sizeof buff, "%a", tm_now );
  printf ( "%s\n", buff );

  if (buff == ime)
  printf ("bravo");
  else
  printf ("TUBL");

  return 0;
}

Why do I allways get "TUBL" response, even if "buff" and "ime" are the same ???

Buff prints out day of the week - Thu, Wed, Fri...

operator== works on string objects, but for C-strings you must use strcmp in string.h

Also, this should have gone in the C forum. Sorry.

My next problem

Code:

Code:

#include <stdio.h>
#include <time.h>
#include <string.h>

int main ( void )
{

while(1)
{

  time_t start_time, cur_time;

         time(&start_time);
         do
         {
                 time(&cur_time);
         }
         while((cur_time - start_time) < 1);

  time_t now;
  struct tm *tm_now;
  char buff1[BUFSIZ]; // PING
  char buff2[BUFSIZ]; // MAIL
  now = time ( NULL );
  tm_now = localtime ( &now );

  strftime ( buff1, sizeof buff1, "%X", tm_now ); //PING
  strftime ( buff2, sizeof buff1, "%w%X", tm_now ); //MAIL
  printf ("%s\n",buff1);
  printf ("%s\n\n",buff2);
  if( strcmp( buff1, "11:26:40" ) == 0 )
     system("./php Command_line.php ");

if( strcmp( buff2, "412:08:20" ) == 0 )
     system("./php posiljanje_na_gmail_za_probo.php ");

//  return 0;


  }
  }

I've got time working now (delay for 1 sec, and run the program at preset time).

My problem now is, that when I run Command_line.php, the php program (ping about 5000 computers) works for about an hour, but then does not continue with my c program.
I want my c program, to continue working after the php program is finished.
What can I do?
