1）利用C\C++语言实现给定的LFSR；

2）通过不同初始状态生成相应的序列，并观察它们的周期有什么特点；

3）利用生成的序列对文本进行加/解密（按对应位作模2加运算）。

给定的LFSR为：-1) the use of C \ C++ language given LFSR

2) to generate the corresponding sequences by different initial state, and observe what are the characteristics of their cycle

3) using the generated sequence of text encryption/decryption (press the corresponding bit for modulo-2 addition operation).

LFSR given as follows:
