1、编写一个程序algo3-1.cpp，实现顺序栈的各种基本运算，并在此基础上设计一个主程序实现如下功能：
（1）初始化栈S。
（2）判断栈S是否非空。
（3）依次进栈元素a，b，c，d，e。
（4）判断栈S是否非空。
（5）输出栈的长度。
（6）输出从栈顶到栈底的元素。
（7）输出出栈序列。
（8）判断栈S是否非空。
（9）释放栈
,1, the preparation of a program algo3-1.cpp, the realization of the order of the stack of basic computing, and on this basis the design of a main program to achieve the following functions: (1) initialize the stack S. (2) to determine whether the stack S is not empty. (3) into the stack element followed by a, b, c, d, e. (4) to determine whether the stack S is not empty. (5) the length of the output stack. (6) output from the Top-stack at the end of the element. (7) the output sequence of the stack. (8) to determine whether the stack S is not empty. (9) release of the stack
