Thread: Anagram C from file

I want to read program which takes word from user and find anagrams for them in file txt. I read this but I have a problem how to read a file and then propertly compare two words. What I do wrong?

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#include <conio.h>


bool if_anagram(char *a, char *b)
{
    
      int dl1 = strlen(a), dl2 = strlen(b);
      
    if(dl1!=dl2)return false;
  
      int licz[127]={}; 
      for(int i=0;i<dl1;i++)
          licz[a[i]]++; 
      for(int i=0;i<dl1;i++)
          licz[b[i]]--; 
          
      for(int i=0;i<127;i++)
          if(licz[i]!=0) 
            return false; 
        
  return true; 
} 


int main(int argc, char *argv[]) {
    
    char a[101], b[8], * buffer; 
    int i=8, n;
    FILE *pFile;


    pFile=fopen("text.txt","r");
    
    printf("Put word: ");
           scanf ("%s", a);
       
    buffer = (char*) malloc (i+1);
  if (buffer==NULL) exit (1);
        
    if (pFile != NULL){
        while(!feof(pFile))
        {
             for (n=0; n<i; n++)
            buffer[n]=fgets(b,8,pFile);
            buffer[i]='\0';
        
            printf("%s\n", b);
            //printf("%p\n", &b);
            
            if(if_anagram(a,b))
                 printf("Word %s is anagram!", b);
                 
         free (buffer);    
        }
      fclose(pFile);
  }
  else{
      printf("File is not exist.\n");
  }
  
      
    return 0;
}

My unit in this program will be each word for several processes.

I know what it involves, but I wanna try this. How to start?
