用递归下降法分析算术表达式的框图，主要完成：
⑴ 通知外界键入算术表达式；
⑵ 控制Ｅ过程分析算术表达式；
⑶ 根据分析结果之正误，分别通知外界不同的信息。
-Analysis of recursive descent method with arithmetic expressions diagram, mainly to complete: ⑴ notice outside type arithmetic expressions ⑵ control process analysis arithmetic expression E ⑶ results are based on an analysis of error, respectively, different information to inform the outside world.
