Top Forums Programming get next working day Post 302272810 by anup13 on Thursday 1st of January 2009 04:54:32 AM

i done some modifications for considering holidays also(i.e local holiday).
also you can get nth working day from given day.
if holiday list is stored in table, you can build hash table on it instead of array of holiday. hash table will give lots of performance gain also

Code:
#include <stdio.h>
#include <stdlib.h>
#include<time.h>


#define OFORMAT "%Y-%m-%d"

//char holidy_list[][12]={"01-Jan-2004","03-Jan-2004","04-Jan-2004","10-Jan-2004","11-Jan-2004","17-Jan-2004","18-Jan-2004"};

char holidy_list[][12]={"2004-01-01","2004-01-03","2004-01-04","2004-01-10","2004-01-11","2004-01-17","2004-01-18"};

int main(void)
{
   struct tm xmas, *tm1;
   time_t tt;

   int flg=0,i,found=0;

   char date[] = "2003-12-31";
   char buf[12];



  int no_of_days =1;  // nth working day 
  int  count =0;

   if (strptime(date, "%Y-%m-%d", &xmas) == NULL)
   {
      printf("strptime() failed.\n");
      exit(1);
   }


    tt = mktime(&xmas);
    tm1 = localtime(&tt);
    strftime(buf,sizeof(buf), OFORMAT, tm1);
    printf("\nOld Date is <%s>\n",buf);

 for(;;)
 {
    tt= tt-86400;
    tm1 = localtime(&tt);
    strftime(buf,sizeof(buf), OFORMAT, tm1);

    //printf("\nbuf<%s>  count<%d>",buf,count);
    found=0;
    if (tm1->tm_wday==0 || tm1->tm_wday ==6)
    {
         continue;
    }

    if(HashGet(buf))
     { found = 1;}

    if(found ==0)
     {
        count ++;
        if (count >= no_of_days)  break;

     }

     //printf("\nbuf<%s> hldlst<%s> count<%d>",buf,holidy_list[i],count);

  }

  for( i = 0; buf[ i ]; i++)
    buf[ i ] = toupper( buf[ i ] );
  printf( "\nNew Date is <%s>\n",buf);
}


int HashGet(char buf[])
{
    int i;
    for(i=0;i< (sizeof(holidy_list)/sizeof("30-DEC-2008"));i++)
    {
      if (strncasecmp(holidy_list[i],buf,sizeof(buf))==0)
        { return 1; break;}
    }
    return 0;
}
