在阅读此文本文件时，找不到哪里出错了

Question

我写这段代码是为了从一个文本文件中读到下面一行：1019*/passed//56。）100,/82//10然而当我在sscanf函数后打印它时，我只得到了1019和数字10，其余的都有垃圾值，知道为什么吗？如果有人能纠正我，我会很感激，我甚至试着在sscanf函数中放入%d而不是仅仅放入%[..]，但是仍然没有打印出所需的值。

 #include <stdio.h>
 #include <stdlib.h>
 #include <string.h>

 int main ()
{
char buffer[100];
char status[20];
int grades[4]= {0};
int id;
int j;
int k;
int temp;


FILE *pointer = fopen ("testing5.txt", "r");
if((pointer = fopen("testing5.txt", "r"))!= NULL)
{
    printf("No error, file successfully opened\n you may contine :)\n");
}
   else
   {printf("file could not be opened\nterminating program,...\n");
   return 0;}
   fgets(buffer,100,pointer);
   printf("%s\n", buffer);
     sscanf(buffer,"%[^*/]*/%[^//]//%[^.).)]%[^,/],/ %[^//]//%d",&id,status, &grades[0],&grades[1],&grades[2],&grades[3]);
    printf("%d\n%s\n%d\n%d\n%d\n%d",id,status, grades[0],grades[1],grades[2],grades[3]);
   for (j =0; j<3; j++)
   for(k =j+1; k<4;k++)
   {
    if(grades[j]<grades[k] )
    {
        temp = grades[j];
        grades[j] = grades[k];
        grades[k] = temp;
    }
   }
   printf("\nthe grades in ascending order is \n");
   for (j =0; j<4; j++)
   {
    printf("%d\n", grades[j]);
   }
  return 0;
 }

  sscanf("1019*/passed// 56.)100,/ 82//10\n", "%d*/%[^/]// %d.)%d,/ %d//%d",
      &id, status, &grades[0],&grades[1],&grades[2],&grades[3]);
