编译原理的一个语法分析程序，设计，编制并调试一个语法分析程序，加深对语法分析原理的理解。可以编译c语言的基本结构，包括循环嵌套和条件嵌套。(1)　　执行程序时，可输入源程序的路径，如果输入为空的话，将会编译默认的源程序“./input.dat”

(2)　　如果编译发现有错误，则会输出错误行数，并在结束编译时输出“Complete!”

-Compilation Principle of a grammar analysis, design, compile and debug a grammar analysis of procedures, better understanding of the analysis of grammar understanding of the principles. Can compile the basic structure of c language, including the cycle of nested and nested conditions. (1) implementation of procedures, they can enter the source path, if the input is empty, it will compile the source code by default　./Input.dat　(2) If the compiler detected the error, it will output the wrong number of rows, and in the end of the compiler output　Complete!
