Program in C closing without explanation

Question

I am doing a C program that aims to read a list of purchases stored in a text file and add the total value of the prices of the products. In each line of the file has, the product name, the quantity available and the unit price. I did all the code and compiled, but the program closes unexpectedly every time it arrives at the part of the code that reads and stores in vectors. Follows the code:

void main() {
   char arqnome[30];

   printf("\nDigite o nome da lista de compras\n");
   scanf("%s", arqnome);
   FILE *arq = fopen(arqnome, "r");

   if (arq == NULL) { printf("\nErro ao abrir o arquivo\n"); exit(1); }

   int linhas = 0;
   int letras = 0;
   char c;

   while (!feof(arq))
   {
       c = fgetc(arq);

       if (isdigit(c) == 0 && c != '\n' && c!= ' ') { letras++; }
           else
           {
               if (c == '\n') { linhas++; }
           }
       printf("\n%d letras", letras);
       printf("\n%d linhas", linhas);
   }

   char **nomeproduto = malloc(linhas * sizeof(char));
   for (int i = 0; i < linhas; i++) {
       nomeproduto[i] = malloc(sizeof(char) * 10);
   }

   int *quantida = (int*)malloc(linhas * sizeof(int));
   int *preco = (int*)malloc(linhas * sizeof(int));

   for (int clean = 0; clean < linhas; clean++) { quantida[clean] = 0; preco[clean] = 0; }

   fclose(arq);
   FILE *arq1 = fopen(arqnome, "r");

   //int i = 0;
   int j = 0;
       for (int i = 0; i < linhas; i++)
       {
           fscanf(arq1, "%s", *(nomeproduto+j));

           fscanf(arq1, "%d", quantida[j]);

           fscanf(arq1, "%d", preco[j]);   

           j++;
       }

   int total = 0;
   for (int k = 0; k < linhas; k++) {
       total = total + preco[k];
   }

   printf("\nA soma dos preocos dos produtos eh %d", total);
   printf("\n");
   fclose(arq1);
   system("pause");
}

According to @Isac

You’re making the fscanf wrong. They should stay that way:

 fscanf(arq1, "%s", nomeproduto[j]);
 fscanf(arq1, "%d", &quantida[j]);
 fscanf(arq1, "%d", &preco[j]);
