使用ODBC访问数据库，一则ODBC是直接封装在MFC库里面的，二则忙着考研没有时间学习dao。 ODBC和DAO用起来可能最大的区别就是ODBC使用之前得先建立数据源，根据不同的数据库，使用的参数也不同。具体请看在这之前的一片文章。里面有许多东西没有说，属于高级技巧性东西，得学你们自己摸索。(Using ODBC to access the database, an ODBC database directly encapsulated in the MFC inside, two busy Kaoyan no time to learn dao. ODBC and DAO can be at the biggest difference is that must be built before using ODBC data source, depending on the database, the parameters used are also different. Details, please read an article before this. There are many things not said, things are high skill, have to learn your own. )

仿射加密法与单码加密法没什么不同，因为明文的每个字母分别只映射到一个密文字母。仿射密码的加密算法就是一个线性变换，即对任意的明文字符x，对应的密文字符为  ，其中，a,b∈Z26，且要求gcd(a,26)=1,函数e(x)称为仿射加密函数。

说明：  I2C_SHT21 温湿度传感器测量 I2C 读取SHT21 温湿度传感器 SHT21驱动库有两种操作模式，适合不同操作 自动转换测量模式： 1：启动任意一个测量指令,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值, autoMeasure(float * th); 该函数读取测量得出的数据，并根据数据的类型进行转化，再自动启动下一个类型的测量 指定转换测量模式： 1：先启动一次测量,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值,例如读取温度执行readT();(2C_ SHT21 temperature and humidity sensor measurement I2C read SHT21 temperature and humidity sensor SHT21 driver library has two operation modes, which are suitable for different operations Automatic conversion of measurement mode: 1: Start any measurement command, for example, measure the temperature and execute measure(); 2: Delay 200ms 3: Read the measured value and Automeasure (float * th); This function reads the measured data, converts it according to the data type, and then automatically starts the next type of measurement Specify the conversion measurement mode: 1: Start a measurement first, for example, measure the temperature; 2: Delay 200ms 3: Read the measured value, for example, read the temperature and execute readt();)
