我有一个家庭链表.我删除了其中一个孩子的兄弟姐妹.
p->myWife->myChildren=p->myWife->myChildren->mySibling; //makes the sibling the child so the list is not broken when deleting
delete p->myWife->myChildren->mySibling;

然后我打印基于此的子/兄弟属性
if(p->myWife->myChildren->mySibling!=NULL){
print the childs attributes
}

每当我打印时,它会为兄弟打印一个奇怪的数字(我假设它的内存地址)我需要做什么才能使该指针为空?

删除指针不会将其设置为零.它只是释放指针指向的内存.要将其设置为NULL,您必须自己将其设置为NULL.
p->myWife->myChildren->mySibling = NULL /*defined to be zero */;
