[Windows Develop] jordan DL : 0: 对以下文法，采用算符优先分析法，对G[S]所定义的赋值语句进行语法分析，并在语法分析过程中将所输入的赋值语句翻译为四元式。-The following grammar, the use of operator priority analysis of G [S] defined assignment for parsing and grammar analysis of the process entered assignment translated into Quaternion type.

[Windows Develop] suanfuyouxian DL : 0: 是一个程序，实现了算符优先文法，本程序最大的特点是算符优先的分析表并不是手动输入的，而是由程序自动分析而成的，构建FIRSTVT集和LASTVT集，最后画出分析表。-Is a process, the priority operator realize the grammar, this process is characterized by the largest operator priority analysis table is not manually entered, but by the procedures derived from automatic analysis, build FIRSTVT sets and LASTVT set, the final draw analysis table.

[Windows Develop] suanshubiaodashiqiuzhi DL : 0: 1、以字符序列的形式从终端输入语法正确的、不含变量的证书表达式。利用一定的运算符优先关系，实现对算术四则混合运算表达式的求值，并且在求值中运算符栈、运算数栈、输入字符和主要操作的的变化过程。 2、设置运算符栈和运算数栈辅助分析算符的优先级。 3、在读入表达式的字符序列的同时，完成运算符和运算数的识别处理，以及相应的运算。 4、在识别处运算符的同时，要将其字符序列形式转换成整数形式。 5、在程序的适当的位置输入运算符栈、运算数栈、输入字符和主要操作内容。 -1, to form a sequence of characters input from the terminal grammar correct, non-variable expression of the certificate. The use of a certain operator precedence relations and the realization of the four mixed arithmetic expression for computing the value, and value in order to stack operator, computing the number of stacks, input characters and major changes in the course of the operation. 2, set up operator stack operands stack and operator-assisted analysis of the priority. 3, in the time sequence of characters into the expression at the same time, the completion of operator and operator identification numbers, as well as the corresponding arithmetic. 4, in the identification Office operator at the same time, to form the character sequence into the form of an integer. 5, in place procedures for the importation of the operator stack, the number of stack operations, input characters and the main operation of the content.

[Windows Develop] shiyan3 DL : 0: ，熟悉分析过程，注意在构造表2时依据“操作符运算优先级和运算符的结合率”原则解决冲突。(2)思考：如要将程序改成SLR四则运算语法分析器，应如何修改文法3为文法4(文法4应还支持减除运算)。(3)思考：要将程序改成SLR四则运算语法分析器，应如何在该程序的基础上修改、增加代码。-Familiar with the process, analysis, pay attention to in the construction of Table 2 for "with the operator priority of operations and operator of rate" principle to solve conflict. (2) think: if the program should be changed to SLR four operations should be how to modify the grammar parser, 3 to 4 (4 grammar grammar should also support the subtraction operation). (3) think: the program should be changed to SLR four operations parser, should how to modify, add the code in the program is based on.
