设计一个栈，要求如下：

1、使用模版技术实现，要求该栈内能存储各种数据类型如int、char、string以及自定义类型

2、设计一个基类，基类定义栈的所有接口，子类来具体实现

3、每个子类使用不同类型的容器来组织底层数据-Design a stack requirements are as follows: 1, using template technology, requires that the stack can store various data types such as int, char, string, and custom type 2, the design of a base class, base class defines all of the interface stack, sub- concrete realization of class 3, each sub-class of different types of containers used to organize the underlying data
