公交路线模拟（在开发有关地理定位的应用程序时，程序中经常需要描述各个地点的位置以及交通路线情况。为了清晰、准确地描述某个地点信息，通常采用图形和文字相结合的方式。本例实现了一个公交路线的模拟程序，利用CStatic控件存储各个站点信息）。(Bus route simulation (in the development of geo-positioning applications, the programs often need to describe the location of various locations and traffic route. In order to clear, accurate description of a location information, usually a combination of graphics and text the way. The Example realization of a bus route simulation program, using CStatic control information stored in various sites).)

通过设计、编制、调试一个具体的词法分析程序，加深对词法分析原理的理解，并掌握在对程序设计语言源程序进行扫描过程中将其分解为各类单词的词法分析方法。 实验内容及基本要求： 设计一个简单的程序设计语言（语言中有+、-运算，语句有赋值语句、输入语句、输出语句、复合语句） 要求: 1.输入源程序，最后以“#”作结束标志； 2.处理各单词，计算各个单词的值和类型； 3.输出各个单词名、单词的值和类型。 (By design, develop and debug a specific lexical analysis procedures, to deepen understanding of the principles of lexical analysis, and mastery of the programming language source code will be scanned in the decomposition process of lexical analysis of various types of words. Experimental content and basic requirements: the design of a simple programming language (language has+,- arithmetic, assignment statement has input statements, output statements, compound statements) requirements: 1 input source, and finally to " #" as. end marker 2 each word processing, calculating the value and type of each word 3 outputs each word name, value and type of the word.)
