i wanted to find the duplicates present in an array of pointers.the code is shown below.when i run this application it is gining segmentation fault.But when i extract this function,i am able to run it just fine.Can anyone please tell me what could `

when i detect the duplicates,i just put those strings to a file named output.txt.

i discovered that when strcmp is used,its giving this segmentation fault.
but when i extract this function and run it on some test code,it works really fine.

```
      main()
      {
           char *a[20];
           DIR             *dip;
           int i = 0;
           dip = opendir("src/my_folder");
           char *condition_var; 

           while ((dit = readdir(dip)) != NULL)               
           {
           condition_var = dit->name;      

            a[i] = condition_var
                            i++;
            }
            findduplicates(a,i);
       }

      char *findduplicates(char *arr[3],int count)
      {
      int i = 0;
      int j = 0;
      int val = 0;
      FILE *output = fopen("output.txt","w");
      for(i = 0;i<count;i++)
      { 
               j = i+1;
       for(;j<count;j++)
       {
             if(strcmp(arr[i],arr[j])==0)
             {
           printf("The index of a duplicate elemnt is %d\n",j);
           arr[j] = " ";

             }
        }

      }
int k = 0;
while(k<3)
{

   printf("the aarray is %s\n",arr[k]);
   fputs(arr[k],output);
   fputs("\n",output);
   k++;
}

```

}`
