This book introduces standard C++ and the key programming and design techniques supported by C++. Standard C++ is a far more powerful and polished language than the version of C++ introduced by the first edition of this book. This book presents eve

这是我上学时的一个作业，使用symetric key和mac给一个聊天程序发送的信息加密和解密。使用c#编写。单机测试的时候，打开2个实例，然后其中一个点listen，另一个的hostname填上localhost，然后点连接。两个chat就可以互相发送信息了。-This is my school, a job, use symetric key and the mac to a chat program to send the message encryption and decryption

CRC-16是检测数据在发送过程中发生错误的常用校验方法，本文通过从工程应用的角度，讲述如何实现CRC-16的程序开发，并给出了Visual Basic和Visual C++程序代码，给从事工业控制的人员在写通信程序的时候提供一些有价值的参考。-CRC-16 is to detect data errors in the process of sending commonly used calibration methods, the paper from the engineering poi
