Help Meeeeee!!!!!!

[salsa]

HI,

I need to tokenize the data from a file named books.dat to load into the system...anyone got any clues?! some help would be greatly appreciated

Book data file format:
<id>:<title>:<author>:<year>:<price>:<count>

Example:
1:A Book on C:A. Kelly:1997:89.95:7
2:Java Software Solutions:J. Lewis:2000:79.95:2
etc...

n so far my code is looking like this...

#include "bookstore2.h"

#define NUM_ARGUMENTS 3
#define MAXSTRING 100
#define ARRAYSTR 100

int main(int argc, char **argv)
{
   int tempID, tempYear, tempPrice, tempCount;
   char tempString[MAXSTRING], DELIMITER[] = ":";
   char* ptr;
   char* tempArray[ARRAYSTR];
   char* booksFile;
   char* salesFile;
   BookListType booklist;
   FILE* fp;

   /*when arguments are wrong*/
   if(argc != NUM_ARGUMENTS)
   {
      fprintf(stderr, "Argument error\n");
      return EXIT_FAILURE;
   }
   else
   {
      /*check what arguments were passed*/
      if((argv[1] == "books.dat") && (argv[2] == "sales.dat"))
      {
         loadData(&booklist, booksFile, salesFile);
         fp = fopen("books.dat", "r");

         /*read data from books.dat*/
         ptr = strtok(tempString, DELIMITER);
         tempID = strtol(ptr, &tempArray, 10);
         newBook->id = tempID;
      
         ptr = strtok(NULL, DELIMITER);
         strcpy(newBook->title, ptr);

         ptr = strtok(NULL, DELIMITER);
         strcpy(newBook->author, ptr);

         ptr = strtok(tempString, DELIMITER);
         tempYear = strtol(ptr, &tempArray, 10);
         newBook->year = tempYear;

         ptr = strtok(tempString, DELIMITER);
         tempPrice = strtol(ptr, &tempArray, 10);
         newBook->price = tempPrice;

         ptr = strtok(tempString, DELIMITER);
         tempCount = strtol(ptr, &tempArray, 10);
         newBook->count = tempCount;

         if(fp == NULL)
         {
            printf("Can't open file\n");
            exit(1);
         }
         fclose(fp);
      }
   }

   return EXIT_SUCCESS;
}

.....with these errors when compiled:

bookstore2.c: In function `main':
bookstore2.c:41: warning: passing arg 2 of `strtol' from incompatible pointer type
bookstore2.c:42: error: `newBook' undeclared (first use in this function)

You have a point; it's in sore need of some code tags.

Note:
Do not add code tags to what you have - instead, copy your code over from the code editing window again, overwriting what's currently in your post, then apply the code tags.

Also, try a more descriptive subject line next time. Your subject line currently sounds like a 10 year old yelling to mommy.

The strtol() issue is the least of your troubles. Is it possible you could attempt some simpler programs before tackling this one? Anyway, this is as good a place as any to start:

      if((argv[1] == "books.dat") && (argv[2] == "sales.dat"))
