异质链表实现：链表主要操作方面：遍历链表时，对应不同的类型对象对象识别问题。通过RTTI可识别类型。-Achieve heterogeneous linked list: list the main operating areas: traverse linked list, the corresponding objects of different types of object recognition. RTTI can be identified by type.

使用C语言实现了异质链表，能够使得链表中传入的数据不局限于同一种类型(Using the C language to implement the heterogeneous linked list, it can make the data from the linked list not limited to the same type)
