在BC或VC环境下用C语言，以面向过程的思想进行程序设计，实现检错功能。程序大致包括以下几个内容：

1.原始报文输入（包括生成多项式）

2.生成加入校验码之后的报文

3.接收方报文输入

4.检错并给出结果显示

-BC or VC in the environment using C language, process-oriented thinking process design, implementation, error detection function. Procedures generally include the following: 1. The original message input (including the generator polynomial) 2. Generated by adding after the packet checksum 3. Receiver input packets 4. Check and give the wrong results
