Thread: Assigning line of file to string

I'm making a game that requires the user to enter a correct username and password to play. I have a list of accepted ones saved in a txt file. How do i read each line of the file and check it with the one entered? I know how to use strcmp(string1, string2). I just need to know how to move from one line to the next. This is what I have for this part of the program so far. Also, I think im using the feof() wrong.

Code:

  id = fopen("F://CS223/namepass.txt", "r");
  score = fopen("F://CS223/scores.txt", "a");
  
  srand(time(NULL));
  
  if(id == NULL)
  {
        printf("ERROR");
  }
  
  else
  {
       printf("Enter your name and password, like this: (name_password)\n\n");
       gets(input);
       while(!feof(id))
       {
            fscanf(id,"%s",passw);
            if(strcmp(input,passw)==0)
            {
                 i=1;
            }   
            else
            {
                 i=0;
            }
       }
       if(i==1)
       printf("\nACCESS GRANTED\n\n");
       else
       {
           printf("\n\nACCESS DENIED\n\n");
           system("PAUSE");
           exit(0);
       }      
       fclose(id);  
  }

read on why feof and gets are bad, depending on the format of your text file , you could use the return value of fscanf() to control your loop,the rest should be straight forward

....
i must add that its pointless to keep on checking the rest of the file when the password has already been found

That's because your code resets i to zero whenever a line is found in the file that does not match user input. So, if there is anything after a match occurs, i will be reset.
