将文本文件转换为结构C的动态数组

Question

I have a text file with this information

 AreaA  500 2   
 AreaB  200 1       
 AreaC  100 2   
 AreaD  1000    1

and I want to put read this information into a dynamic array of structures I made this struct

  typedef struct dadosZoo zoo, *pZoo;
  struct dadosZoo {
     char AreaID[ID_TAM];
     int capacidade;
     int adjacentes;
     //areas adjacentes
  }; 

and then i created a function 'area_Estrutura' which was supposed to read the file and put the information into a dynamic array of structures.

 void area_Estrutura(char *nomeFich, zoo *z){
    FILE *f;
    /* int cap, adj;
    char areId;*/
    //zoo *z;

    f = fopen(nomeFich, "r");
    if (f ==NULL){
       printf("Erro na abertura do ficheiro %s para leitura.\n", nomeFich);
       return;
    }

    while(fscanf(f, "%c\t%d\t%d\n", &z->AreaID, &z->capacidade, &z->adjacentes)!=EOF){
        z = malloc(sizeof(zoo));
        if(z!=NULL){
           fscanf(f, "%c\t%d\t%d\n", &z->AreaID, &z->capacidade, &z->adjacentes);
           fprintf(f, "%s\t%d\t%d\n", z->AreaID, z->capacidade, z->adjacentes);
           free(z);
        }

     }
 fclose(f);

} 

I never know how many structures but one line is one structure so I did this

 while(fscanf(f, "%c\t%d\t%d\n", &z->AreaID, &z->capacidade, &z->adjacentes)!=EOF)

that reads the file while not end of the file in this line i don't know if i should read it like that or with the variables that i created up there

 char areId;
 int cap, adj;

then in the main i put this call to function

   zoo *zoo;
   area_Estrutura("Zoo.txt", zoo);

and i wanted it to print on the screen. when i build the code i don't have any mistakes or warnings but it doesn't run. Does someone have any idea. Sorry if the formatation or the english is a little bit confusing but it is not my mother toungue, thank you.

You need to change fscanf(f, "%c\\t%d\\t%d\\n", &z->AreaID, &z->capacidade, &z->adjacentes) to fscanf(f, "%s\\t%d\\t%d\\n", z->AreaID, &z->capacidade, &z->adjacentes)

ie %c to %s and do not pass address of areadID
