warning: assignment makes pointer from integer without a cast

Code:

---


#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
#include <errno.h>
 
int main(int argc,char **argv)
{
  char ch[1000];
  int max = 1000;
  int i = 0;
  DIR        *dip;
  struct dirent    *dit;
  FILE *fp;

  char* result = NULL;
  char delims[] = {'(', '.' , ')'};
  /* read character by character from stdin */
  if((dip = opendir(argv[1])) == NULL){
    perror("opendir");
    return 0;
  }
   
  while((dit = readdir(dip)) != NULL){
    fp = fopen(dit->d_name, "r");
    printf("%s\n",dit->d_name);
    while (fgets(ch, sizeof(ch),fp ) != NULL){
      result = strtok( ch, delims );
      while( result != NULL ) {

      }
      //printf("%s ",ch);
      i++;
    }
  }
  printf("\n");
  return 0;
}

Okay i know this is common but I get that warning every time i use the strtok command I is there a reason i dont even using integers so..... im not sure if its "result" thats the problem

Use the following program.It will not get warning.

Code:

---


#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
#include <errno.h>
#include<string.h>
#include<stdlib.h>

int main(int argc,char **argv)
{
  char ch[1000];
  int max = 1000;
  int i = 0;
  DIR        *dip;
  struct dirent    *dit;
  FILE *fp;

  char* result = NULL;
  char delims[] = {'(', '.' , ')'};

  if(argc<2)
  {
          printf("Give any directory\n");
          exit(1);
        }
  /* read character by character from stdin */
  if((dip = opendir(argv[1])) == NULL){
    perror("opendir");
    return 0;
  }

  while((dit = readdir(dip)) != NULL){
    fp = fopen(dit->d_name, "r");
    printf("%s\n",dit->d_name);
    while (fgets(ch, sizeof(ch),fp ) != NULL){
      strcpy(result , strtok( ch, delims ));
      while( result != NULL ) {
        printf( "result is \"%s\"\n", result );
        strcpy(result , strtok( NULL, delims ));
      }
      //printf("%s ",ch);
      i++;
    }
  }
  printf("\n");
  return 0;
}

Hope this changes will help

Code:

---

if ( fp != NULL) // Check before reading a directory
    while (fgets(ch, sizeof(ch),fp ) != NULL){
      result =(char *) strtok( ch, delims );  // type cast to avoid warnings
      while( result != NULL ) {
        printf( "result is \"%s\"\n", result );
        result =(char *) strtok( NULL, delims ); // type cast to avoid warnings
      }

---

> fp = fopen(dit->d_name, "r");
What about calling fclose() at some point.

> result =(char *) strtok( NULL, delims ); // type cast to avoid warnings
And what warning would that be?
I see no reason for a cast here.

Code:

---

char delims[] = {'(', '.' , ')'};

---

Anyone else see a problem passing that into the strtok function as the second argument?
