Question

The program I have reads the file, displays it accordingly, but then when trying to view the contents again, they are gone.

Structure:

typedef struct friends_contact {
    char *First_Name;
    char *Last_Name;
    char *home;
    char *cell;
} fr;

Main:

int main() {
    fr friends[5];
    char buffer[BUFFSIZE];
    int counter = 0;
    int i = 0;

    menu(friends, &counter, i, buffer);

    getch();
    return 0;
} 

If statement in the menu function used to open up the file:

if (user_entry1 == 1) {
  printf("Please enter a file name");
  scanf("%s", user_entry3); 

  read = fopen(user_entry3, "r");
}

If statement that allows the user to choose to look at the contacts of the address book.

if (user_entry == 4 ) {
  print_contact(friends, counter, i, user_entry3);
  if (user_entry1 == 1) {
    file2(friends, counter, i, buffer, read);
  }
} 

Read function:

char file2(fr *friends, int *counter, int i, char buffer[], FILE *read) {
  while (fscanf(read, "%s", buffer) != EOF) {
    friends[i].First_Name = malloc(BUFFSIZE * strlen(buffer));
    strcpy(friends[i].First_Name, buffer);
    return printf("\n""%s ", friends[i].First_Name);       
  }  
  fclose(read);
}

If you need me to provide any more code. I’m trying to get it to read the content from the file into the contacts list so I can view, search, or delete them.

P.S. I understand some of the other code may not be perfect, but right now I’m just concerned about figuring this out :).

You have to reset your file pointer using fseek to the beginning of the file again. Your read function should start like:

fseek(read, 0, SEEK_SET); // set file pointer to the beginning of the file
