Thread: someone help? strtol?

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...

Code:

#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)

bookstore2.c:55: warning: passing arg 2 of `strtol' from incompatible pointer type
