:runtime error: member access within null pointer of type ‘struct ListNode‘报错

该问题为刷力扣时,常见报错。错误原因:通常是之前为structListNode分配了内存,但是其中指针未分配地址,导致系统认为其为野指针。解决方案:如果为空,就令其指向NULL如果不为空就加入判断语句。下图提交时,while总是报这个错误。 while(pro->next->valnext!=NULL&&pro!=NULL)/*提交总是报错,后更改pro->next!=NULL判断位置得到修正。如下*/while(pro->next!=NULL&&pro!=NULL&&pro->next->valnext;}s=(LinkList)malloc(sizeof(LNode));s->val=nu

dephi RTI (Runtime Type Information)获取运行时的控件信息

varEdit:TComponent;beginEdit:=FindComponent("Edit1");IfEditisTEditthenTEdit(Edit).Text:='你好Delphi7';end;  RTTI(RunTimeTypeInformation):运行时类型信息,就是在程序运行后也能得到类型(譬如TButton类)的信息. 这在早期主要用于IDE设计时,譬如把一个Button放到窗体后,此时我们的程序虽然没有运行,但在Delphi的IDE编辑环境中,这个Button已经是在运行状态(要不然IDE怎么才能显示我们要求的TButton呢);此时我们对Button的属性等信息的
