是将输入的源程序进行划分，给出基本符号（token）的序列，并掠过注解和空格等分隔符号。基本符号是与输入的语言定义的词法所规定的终结符。 本实验要求学生编制一个读单词过程，从输入的源程序中，识别出各个具有独立意义的单词，即基本保留字、标识符、常数、运算符、分隔符五大类。并依次输出各个单词的内部编码及单词符号自身值。（遇到错误时可显示“Error”，然后跳过错误部分继续进行 -Is the input source program division, and gives the basic

语法分析程序的输入文件为语法分析产生的token串，并在文件最后一列加上了一个#号，代表语法归约结束，程序采用的是递归子程序的方法，如果归约成功会输出Success，如果归约失败，会返回归约到token串的哪个元素出现错误，已经相应的未归约成功的文法产生式是哪条-Parser to parse the input file generated token string, and the last one in the file plus a# sign, on behalf of the end

This paper attempts to address these questions by proposing a new local feature extractor to generalize and complete LBP, and we name the proposed method completed LBP (CLBP). In CLBP, a local region is represented by its center pixel and a l
