[Data structs] sy3-ex DL : 0: 算符有限分析法 //程序功能： //根据算符优先分析法，将表达式进行语法分析，判断一个表达式是否正确。 //文法：E→E+E E-E E*E E/E (E) i // 其中i为无符号整数-operator limited analysis// procedural functions :// operator under priority analysis, to conduct regular expression syntax analysis, judgment, an expression is correct.// Grammar : E E E E-E E E* E/E (E) i// for which i unsigned integers

[Data structs] Precede DL : 0: 用算符优先法对算术表达式求值的过程。要求以字符序列的形式从终端输入语法正确的、不含变量的整数表达式。实现对算术四则混合运算表达式的求值，并在求值中运算符栈、运算数栈、输入字符和主要操作的变化过程。-Operator priority method with arithmetic expression evaluation process. Request to form a sequence of characters from the terminal input grammar correct, non-integer variable expression. 4 to realize a mixed computing arithmetic expression evaluator, and evaluation of operator stack, stack operands, input characters and major changes in the course of operation.

[Data structs] biaodashi.cpp DL : 0: 表达式求值以字符序列的形式从终端输入语法正确的、不含变量的数据表达式。利用教科书表3.1给出的算符优先关系，实现对算术四则混合运算表达式的求值，并仿照教科书的例子3-1演示在求值中运算符栈、运算数栈、输入字符和主要操作的变化过程.-Expressions evaluate to the form of a sequence of characters from the terminal input grammar correct, non-variable expression data. Table 3.1 using the textbook are given priority to the relationship between the operator, to achieve four mixed computing arithmetic expression evaluation and follow the textbook example of the value of 3-1 in the demonstration in order to stack operator, computing the number of stacks, enter the characters and the main operation The process of change.
