本程序是用pascal语言编写的编译原理小程序，包括词法分析，语法分析，语意分析，优化及目标代码生成-this procedure is used pascal language compiler principles of small programs, including lexical analysis, grammar analysis, semantic analysis, optimization and object code generation

C_minus语言的BNF语法定义 程序由声明的列表(或序列)组成，声明可以是函数或变量声明，顺序是任意的。至少必须有一个声明。接下来是语义限制(这些在C中不会出现)。所有的变量和函数在使用前必须声明(这避免了向后backpatching引用)。程序中最后的声明必须是一个函数声明，名字为main。注意，C－缺乏原型，因此声明和定义之间没有区别(像C一样)。-C_minus BNF language syntax definition of procedures from the list of statement (or sequence), with a statement can be variable or function statement, the order is arbitrary. There must be at least one statement. Next is the semantic constraints (these will not arise C). All the variables and functions to be used in the statement (which avoids the use Backpatching backwards). Procedures must be the last statement is a function declaration, the name of the main. Attention C- lack of a prototype, and the definition of a statement is no difference between (the same as C).

编译原理与实践本书介绍了PDF格式的经典系统、编译理论与技术，还包含了当前面向对象语言等比较新的语言编译技术。本书更有价值的是提供了一个较为完整的教学实践适用的样本语言，是一本理论与实践相结合的内容，不可多得的书籍。本书可作为高校教材、教师参考书，以及科研人员的编撰参考。

我做的不好呀，请大家指教。- I do am not good, asks everybody to advise.

解法:对原文法消除左递归,根据消除左递归后的等价文法建立语法树,而后对此语法树 进行后根遍历,即可得到后缀式.- Solution: Eliminates the left recursion to the original grammar, after equal in value grammar establishment grammar tree which eliminates the left recursion, after but the grammar tree carries on the root to spread the calendar regarding this, after then obtains decorates the type

Grammatica is a C# and Java parser generator (compiler compiler). It improves upon simlar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. It supports LL(k) grammars with an unlimited number of look-ahead tokens.
