偶写的链表、堆栈、队列的集合操作_C/C++教程

偶写了一个程序，它的功能是将链表、堆栈、和队列进行集合操作，可以处理一般的插入N个元素，删除N个元素，以及入栈出栈的问题。
--------本程序的最大的特点是能够准确的显示当前的集合操作的各个元素的状态，并且能够将队列的数据以堆栈的格式输出，同样也支持将堆栈的数据以队列的格式显示出来，报错功能也不错，程序的最后将我们开辟的所有的结点空间全部释放掉。偶觉得，数据结构，说白了就是个哪个先进哪个先出的问题，大家觉得呢？？ -----------------偶的QQ:37170732，欢迎喜欢编程的同学加我，非凡是爱好Win32和MFC的同学，大家一起来讨论哦！ -----------------------------下面是程序的代码------------------------------------------
