用C++编写的一个编译器，功能很强大，花了我两个月时间，是编译原理一个大作业。-With C++ Prepared a compiler, function very strong, I spent two months compiling principle is a big operation.

用C++写的由扩充C0文法写成的编译为MIPS汇编的编译器，在MARS4.2上完美测试通过，支持递归、函数定义、函数调用、数组、四则运算、输入输出等，是我本科花了2个月写的大作业，也留给北航的学弟学妹参考。-Written by C++ grammar written by the expansion of C0 compiler for MIPS assembler compiler tested on MARS4.2 perfect support recursive function de
