Thread: It wont display my string

sorry about all the post but at least on my computer it is looking really weird, third times a charm


after sending a string to my main struct it wont allow me to print what is in the struct outside of the function in which i assigned it.

Code:

int buildRooms(char filename[], struct Room list[])
{
  char id[2];
  char roomname [20];
  char north[2];
  char east[2];
  char west[2];
  char south[2];
  char sentence [100];
  char space[4];
  FILE *f = fopen(filename, "r");
  if (f == NULL) {
    fprintf(stderr, "Error opening game file %s./n", filename);
    return 42;}              // failure                                                                   
  else{
      fscanf(f,"%s%s%s%s%s%s",id, roomname, north, east, west, south);
      fgets(space, sizeof(space),f);
      fgets(sentence, sizeof(sentence),f);
      struct Room list;
      strcpy(list.id, id);
  }
 fclose(f);
  return 0;                  // success                                                                   
}
void runGame(struct Room list[]){
  char input;
  printf("Welcome to the Haunted Mansion!\n");
  printf("Type c for current room, n/e/w/s for north/east/west/south.\n> ");
  printf("%s", Room->list->id);
}

why wont it print out what is in the struct, it just ends the program as if the command wasnt there

So use %c as the format.

but it is a string, or so i think, i have it set as char id [2]

Code:

else{
      fscanf(f,"%s%s%s%s%s%s",id, roomname, north, east, west, south);
      fgets(space, sizeof(space),f);
      fgets(sentence, sizeof(sentence),f);
      struct Room list;
      strcpy(list.id, id);
  }

The "list" in the scope of the else statement block takes precedence over the "list" in the parameter list. C has something called the rules of scope, which explain how scope works, and deals with name conflicts. A name conflict is what just happened to you.

This page is one of the most uncomplicated, IMO, articles on the subject. Supplement this with C specific material that you find on the web.
