readdir() gives "." and ".." and doesn't exclude some folders

I was trying to make an interactive directory menu.
But in the directory where he has to read, there are a few directories that i don't want my menu to show and the "." and ".." still shows to...

I just changed all my specific names so you can modify it easier...

please help me, and here is my code..

Code:

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

#define dir getenv("HOME")

main()
{
DIR *dip;
struct dirent *dit;
int i = 1;
int n = 0;
char list_dir[20];
char* list_var[8];

dip = opendir(dir);
  if (dip == NULL)
    {
      perror("opendir");
      return(CODE);
    }
  while (( dit = readdir(dip)) != NULL)
    {
    start:
    sprintf(list_dir,"%s",dit->d_name);
    if (list_dir = "bad_dir"){goto start;}
    if(list_dir == "."){goto start;}
    if(list_dir == ".."){goto start;}
    printf("\t\t\t(%d) %s\n",i,list_dir);
    list_var[n] = list_dir;
    i++;
    n++;
    }
  if (closedir(dip) == -1)
    {
      perror("closedir");
      return 0;
    }
}

at the end there was a switch for the choice list and list_var[n] was a variable that takes the the name of the dir chosen, for further use...

But the problem here...
1 -> it still doesn't exclude the "." ".." and "bad_dir" from my list
2 -> my list_var always give the last dir in my case always the ".." :-(

Please give me some help i've changed this code 100 times but can't find a good solution.

== has never and will never compare strings. strcmp compares strings.

And

Code:

if (list_dir = "bad_dir"){goto start;}

has never and will never give you the comparison you want.

Also, your use of goto has given you an endless loop. What you really want instead of "goto start" is "continue". The continue statement will take you back to the beginning of the loop (like your goto), and it will run the evaluation statement again (readdir) which is what you need to avoid an endless loop.

yes... :-D

this is my first program i'm writing and it takes a long time... certainly because i still have to learn a lot...
Thanks for all the reply's and answers...
