Strange problem

Hi,

Could anyone please explain this problem to me?
I use:

Code:

while(!feof(f))
		  {
			fgets (all_id, 100 , f);
			sscanf (all_id,"%*s %s %s",a_id,d_id);
			str[i] = a_id;
                        printf("\n%s",str[i]);
			strtok(a_id,"G");
			ida = strtok (NULL, "G");
			idsa[i]=atoi(ida);
			
			i++;
			
		  }

printf("\n%s",str[2]);

Even if I use strncpy in place of strtok, the value retained by the str is the last value assigned to it using str[i]=a_id!
Why cannot the str retain its value outside loop?
I'll be obliged if anyone could explain this fundamental misconception of mine?

Thanks,
Angkar

Precisely I see its a stale value! When I switch back to strtok again, its throwing the value of the last result that I got using strncpy!!!

Try changing the loop to something other than feof. Why it's bad to use feof() to control a loop It can cause some wierd things about how many times the loop runs. Fix that, it might help.

Sticking to one thread and not spamming the board would help.
