hi
i can read the records. here the code is..
/*finding the difference btween times*/
#include <stdio.h>
#include<ctype.h>
#include<time.h>
main()
{
char buf[1000];
char dummy[50],dates[11],times[9];
int day,month,year,hour,minute,second,jobid;
FILE *ptr;
clrscr();;
ptr = fopen("read.txt","r");
while (feof(ptr) == 0)
{
fgets(buf, 1000, ptr); /* Read next record */
if(isdigit(buf[0]))
{
sscanf(buf,"%d %s %s %s %s %s
%s",&jobid,dummy,dummy,dummy,dummy,dates,times);
printf("\n\n\n\n\n\n\n\n %d %s %s",jobid,dates,times);
sscanf(dates,"%d/%d/%d",&month,&day,&year);
printf("\n\n\n%d %d %d",month,day,year);
sscanf(times,"%d:%d:%d",&hour,&minute,&second);
printf("\n\n\n %d:%d:%d",hour,minute,second);
}
/* printf("%s",buf); O/P the record to the screen */
}
}
in this code how can i go to the next records? here i can get only
one record.. then here i want to do time difference between two
records..
