c - 从链表中删除某些数字(递归)

Question

大家好，我正在尝试创建一个删除特定数字的函数从链接列表中具有此编号的所有单元格中，但我的删除功能仅删除他到达末尾的第一个单元格，然后返回到主单元格这是我的代码:

struct num* deleteCell(struct num* point, int numdelete)
{
    struct num* tempdelete = point;
    if (point == NULL)  // found the tail and dont found any match to delete
    {
        printf("not found\n");
        return NULL;
    }
    else if (point->number == numdelete)// found one to delete
    { 
        tempdelete = point->pNext;
        free(point);
    }
    else// Just keep going 
    { 
        point->pNext = deleteCell(point->pNext, numdelete);
    }
    return tempdelete;
}

(point是指向第一个单元格的指针，numdelete是我要删除的数字)感谢各位帮忙!!!!

单独

Answer 1

struct num* deleteCell(struct num* point, int numdelete) {
  if (point == NULL) {
     return NULL;
  }

  if (point->number == numdelete) { 
    num* tempdelete = point->pNext;
    free(point);
    return deleteCell(tempdelete, numdelete);
  }

  point->pNext = deleteCell(point->pNext, numdelete);
  return point;
}
