这个题可以使用switch-case语句来解决，首先创建简单文本扫描器，然后从键盘读入0~9或字母a，然后通过开关语句进行匹配，进而输出结果，代码如下：

经过一定的选择过后会罗列出一大段运势数据,而这些是按一定次序进行罗列出来的.
设置一组数字矩阵,矩阵中每个数字都对应于一项星辰运势
每个星座可以设置多个选项,除了星座选择外,还可以根据相同星座的不同日期段(如0号到3号,3号到6号.....),以及血型(o,a,b...)或者属相(鼠,牛,虎....)
举例:
数据假设分四类,一日期,二血型,三属相,四星座
日期 a1,a2,a3,a4....
血型 b1,b2,b3,b4....
属相 c1,c2,c3,c4....
星座 d1,d2,d3,d4....
获取数据用户输入信息,如a2,b3,c1,d2
从而获取对应位置的数据存储地址,从地址读出数据并显示
可以对用户输入信息做一定的运算,根据前后数据的关系,如输出信息分四部分,分别为y1=f(abcx),y2=f(abcx),y3=f(abcx),y4=f(abcx),经过一定运算后将其特定地址的内容显示出来即可,只要注意处理运算超界问题 程序就可以很好的运行了
