一简单小型类pascal语言编译器的词法分析程序,附详细的实验报告-a small category pascal simple language compiler of lexical analysis procedures, with details of the experimental report

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).

语义分析器，将语义分析程序编制成子程序，在语法分析器分析出各语法单位后，分析其含义，并将可执行语句或表达式翻译为四元式输出，并将错误信息输出。-Semantic analyzer, semantic analysis program compiled subroutines, in the parser analyzes the syntax of the unit, analyze its meaning, and translated into an executable statement or expression quaternary-output, and error information output.

编制一个词法分析程序，从输入的源程序中，分析出各个具有独立意义的单词，即基本保留字、标识符、常量、运算符、界符五大类。并依次输出每类单词，错误时记下出错的行列，出错原因，然后跳过错误部分继续分析-compiled a lexical analysis procedures from the importation of the source, the analysis of the various independent significance of the word, that is to retain the basic character identifier, constants, and Operators, the industry address five major categories. And each type of output followed by the words, the wrong way down the ranks wrong, wrong reasons, then jump to the wrong part analysis

c51的一些综合的应用-C51 integrated application

本程序实现了简单的编译器功能，是用PL0语言编写的，思路明确-This procedure achieved a simple compiler function is PL0 languages, ideas clearly

我也不知道好不好的- I did not know is good ha-ha

一个简单的编译器，可以实现简单的画图语句的解析，最终画出简单的图形。涉及程序编译器的实现几个步骤，词法分析，语法分析，语义分析，等等。-a simple compiler can achieve a simple drawing of analytic statement, the final draw simple graphics. The procedures compiler in several steps, lexical analysis, grammar analysis, semantic analysis, and so on.
