说明： 递归运算（栈的应用）的c++程序。程序首先给出链式栈节点类定义，然后给出了实现，最后进行了操作测试，并输出结果。
recurve.cpp就是程序
recurve.txt是运行结果 (recursive algorithm (Application Stack) c procedures. Procedures is the first chain Stack node definition, and then given the realization of the final testing, and output results. Recurve.cpp procedure is recurve.txt is running results)
