编译原理 实现多个表达式的识别和判断出错

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.

C编译器源码是我到处找来的,看了之后很有收获-C compiler source is found everywhere, and found the great harvest

构造实验一所给文法（应考虑改造）的FIRST集合和FOLLOW集合；构造LL(1)分析表；构造预测分析的总控程序；利用分析表、分析栈和总控程序对源程序进行自上而下的语法分输出整个语法分析过程中栈的变化过程及分析结果，如符合语法规则输出“正确”，否则输出“错误”。 -Experiment to construct a grammar (should consider the transformation) of FIRST and FOLLOW set of the collection construct LL (1) analysis table structural prediction analysis of the master control procedures the use of analytical tables, analyze the stack and the total source code control procedures carried out since the last sub output down syntax parsing process of the whole stack and analysis of the results of the change process, such as the grammatical rules out the " right" , otherwise output " error."

《编译原理实践教程》中的程序作了一些扩展，可以将程序转化成四元式。 本人认为书上的程序极为垃圾！- "Translation Principle Practice Course" the center procedure has made some expansions, may transform the procedure four Yuan types. Myself think in the book procedure extremely trash!
