Thread: strstr() - Not able to get it to work.

Hi. It's me again. Can anyone figure why the first code listing, doesnt work despite passing in the correct values?

Whereas if I hardcode the values in the 2nd listing, it works.




Listing One.

Code:

int PartialFind(char *f)
{
 node *curr = NULL;
 curr = LastNode;
 while(curr)
 { 
  if(strstr(curr->IC,f)==NULL)
     return 0;
  else
  {
     printf("Found!");
     return 1;
  }
  curr = curr->Next;
 }
 return 0;
}

Listing Two:

Code:

int PartialFind(char *f)
{
 node *curr = NULL;
 curr = LastNode;
 while(curr)
 { 
  if(strstr("HairyPotter","airy")==NULL)
     return 0;
  else
  {
     printf("Found!");
     return 1;
  }
  curr = curr->Next;
 }
 return 0;
}

Also, your code is rather weird, you have a while loop, but inside that loop you have an if statement that if true, returns from the function, and if false, returns from the function. What is the point of a loop in that case?

LOL. Silly me. Got it. I got what you meant.

I'll try again.

This looks better

Code:

int PartialFind(char *f)
{
 node *curr = NULL;
 curr = LastNode;
 while(curr)
 { 
  if(strstr(curr->IC,f)!=NULL)
  {
     printf("Found!");
     return 1;
  }
  curr = curr->Next;
 }
 return 0;
}
