[Other] DATA_STRUCTURE DL : 0: 题目: 算术表达式求值的程序设计初始条件：表达式计算是实现程序设计语言的基本问题之一，也是栈的应用的一个典型例子。设计一个程序，演示用算符优先法对算术表达式求值的过程。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。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。 -Title: Arithmetic expressions evaluate the initial conditions of the program design: expression of the calculation is to achieve programming language one of the fundamental issues, but also stacks of applications a typical example. Design a procedure to demonstrate the priority method of arithmetic operator expression evaluation process. Sequence of characters in the form of input from the terminal grammar correct, non-integer variable expression. Using the textbook Table 3.1 gives the operator precedence relations, the realization of the four mixed computing arithmetic expression evaluation, and follow the textbook demonstration cases 3-1 in order to value stack operator, computing the number of stacks, input characters and the main operation processes.
