a) 启动程序，请求输入测试程序名，键入程序名后自动开始词法分析并输出结果；
b) 输出结果为单词的二元式序列（样式见样板输出1和2）；
c) 要求能发现下列词法错误和指出错误性质和位置：
非法字符，即不是SAMPLE字符集的符号；
字符常数缺右边的单引号（字符常数要求左、右边用单引号界定，不能跨行）；
注释部分缺右边的界符*/（注释要求左右边分别用/*和*/界定，不能跨行）
a) Start the program, request to input the name of the test program, input the name of the program, start the lexical analysis automatically and output the results;
b) The output is a binary sequence of words (see template output 1 and 2 for styles);
c) It is required to find the following lexical errors and point out the nature and location of the errors:
Illegal characters, which are not symbols of sample character set;
The character constant is missing the single quotation mark on the right (the character constant should be defined with single quotation mark on the left and right, and cannot cross lines);
The annotation part lacks the right boundary * / (the annotation requires the left and right sides to be delimited by / * and * / respectively, and cannot cross lines) (2021-02-18, C/C++, 1KB, 下载0次)
以STC89C52单片机为核心；然后结合各个模块设计来完成小车的功能，采用光敏二极管和电压比较器从而把反馈到的信号送入单片机，从而完成寻光功能；采用红外对接管检测，完成避障功能；采用驱动芯片，控制小车在各区域按预定的速度行驶；采用LED数码管来实时显示小车里障碍物距离；供电方面主要是以锂电池为电源。该设计方案的优点是针对普通智能小车在避障过程中无法准确寻找光源，或是在寻光过程中无法避障的缺陷，
STC89C52 MCU as the core; then combined with the design of each module to complete the function of the car, using photodiode and voltage comparator to feed the feedback signal into the MCU, thus completing the light seeking function; using infrared docking detection, to complete obstacle avoidance function; using driver chip to control the car in each region at a predetermined speed; using LED digital tube to achieve the reality. When displaying the distance of obstacles in the car, the main power supply is lithium batteries. The advantage of this design scheme is that the ordinary intelligent car can not accurately find the light source in the process of obstacle avoidance, or can not avoid the defects in the process of light seeking.

改进的MadEdit源码，增强了16进制编辑功能，可通过对话框修改每行编辑的字节数(最大256字节)，并移植到codeblocks集成开发环境中，内含编译说明，MadEdit是我目前最喜欢的源代码和16进制编辑器
The improved MadEdit source code enhances the hexadecimal editing function. It can modify the number of bytes edited per line (up to 256 bytes) through a dialog box and migrate to the CodeBlocks integrated development environment. The compiler explains that MadEdit is my favorite source code and hexadecimal editor at present. (2018-10-26, C/C++, 7845KB, 下载2次)
