Errors while creating a graph in C - c

Question

I'm trying to generate a graph from a matrix but I'm having some problems, here is the code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_N 10
#define MAX_P 20
//Declaracion del TDA cola
typedef struct Node {
int rafaga;
int id;
struct Node *dret;
struct Node *esq;
int fiscals;
int funcionaris;
int advocats;
} tipoNodo;
typedef tipoNodo *pNodo; // tipo para declarar nodos a un entero
int nodes = 0, funcionarisTotals = 0, advocatsTotals = 0, fiscalsTotals = 0;
Node llista[MAX_N];
int graf[MAX_N*2][3];
void crearGraf(int graf[MAX_N*2][3]) {
FILE *pf;
char caracter; // variable de tipo caracter que va a servir para almacenar los caracteres leidos del archivo
int valor, o, d;
pf = fopen ("graf.txt","r"); // se abre el archivo en forma de lectura
if (!pf) { //en el caso que no se pueda abrir el archivo se manda un mensaje de error
printf ("ERROR: el fichero no existe o no se puede abrir\n");
exit(-1); //mensaje "presiona una tecla para continuar"
}
else {
int arestes = 0;
while (!feof (pf)) {
int j = 0;
nodes = int ((caracter=fgetc(pf))-'0');
printf ("El graf te %d\n nodes", nodes);
for(int i = 0 ; i < nodes ; i++) {
llista->[i].id = i;
llista.[i].rafaga = 1;
}
caracter = fgetc(pf);
o = int ((caracter = fgetc(pf))-'0'); //nodo origen
caracter = fgetc(pf);
d = int ((caracter = fgetc(pf))-'0');//nodo destino
caracter = fgetc(pf);
valor = int ((caracter =fgetc(pf))-'0');//pes de l'aresta
if (o < 0 || d < 0 || valor < 0) break;
printf ("%d %d %d\n",o,d,valor);
graf[o][d] = valor; // es guarda el pes de l'aresta que va de X -> Y a la matriu
arestes++;
}
fclose (pf);//se cierra el fichero
for(int j = 0; j<arestes ; j++) {
if(j == 0) {
llista[graf[j][0]]->dret = llista[graf[j][1]]; // enllacem l'aresta primera
}
if(j != 0 && (graf[j-1][0] == graf[j][0])) {
llista[graf[j][0]]->esq = llista[graf[j][1]]; // enllacem l'aresta esquerra
}
else {
llista[graf[j][0]]->dret = llista[graf[j][1]]; // enllacem l'aresta dreta
}
}
}
}
int main (void)
{
int graf[MAX_N][MAX_N];
crearGraf(graf);
return 0;
}
The error I'm getting is:
SC.c:57: error: expected unqualified-id before ‘[’ token
SC.c:58: error: expected unqualified-id before ‘[’ token
Which are these two lines in the for loop:
for(int i = 0 ; i < nodes ; i++) {
llista->[i].id = i;
llista.[i].rafaga = 1;
}
I think I don't understand really the TYPE of variable I'mworking with here.
Could someone give me a hand? I've been trying to look for similar problems but I couldn't fix mine.
Thanks!

Change these 2 lines to
llista[i].id = i;
llista[i].rafaga = 1;
and you will be accessing the things that you appear to be trying to access.
Using the -> operator dereferences a pointer while it appears that you just want to access array elements which is done as above. I cannot speak for the correctness of the remainder of your code but these changes at the least should remove your compiler errors.
