Thread: check if the word exists in file

hello ..
i have a question
i have file of words ( dictionary) and i have another file(list) with list of words that could be or could not be in (dictionary)
so i need to read from (List) and check if it exist in (Dictionary)
and i want to check if the word exist or not .. help me out please , i couldn't figure it out

Code:

#define LENGTH
int main(void)
{
  FILE *Dict_f;
  FILE *Word_f;
  int w, index, s;
  char word[LENGTH];             
  
  // open the dictionary file
  Dict_f = fopen("Dictionary.txt", "r");
  // check if the file opened
  if (Dict_f == NULL) {
    printf("Couldn't Open File: Dictionary.txt!\n");
    exit(-1);
  }
  
  // open the test text file
  Word_f = fopen("list.txt", "r");
  // check if the file opened
  if (Word_f == NULL) {
    printf("Couldn't Open File: list.txt!\n");
    exit(-1);
  }

  //extracting the word
  do {
    w = fscanf(Word_f, "%s", word);
    s = strlen(word);
    CheckExist(word)            // function to check if the word exist in Dict_f or not
  } while (w != EOF);           /* repeat until EOF           */
  
  fclose(Word_f);
  fclose(Dict_f);
  
  return 0;
}

i know i should use sth like strcmp but what other condition with it ?

if (strcmp(word, ...)==0)


thank you !

You need to compare each word from the list.txt with every word from the Dictionary.txt.

Yeah, that might have been me trying to clean up the mess - I think it was something like #define LENGTH 20
