1）用C\C++语言实现单表仿射（Affine）加/解密算法；

2）用C\C++语言实现统计26个英文字母出现频率的程序；

3）利用单表仿射加/解密程序对一段较长的英文文章进行加密，再对明文和密文中字母出现的频率进行统计并作对比，观察有什么规律。-1) C \ C++ language to achieve a single table Affine (Affine) encryption/decryption algorithm

2) C \ C++ language statistics program 26 English letters appear frequency

3) Using a single table affine encryption/decryption program for a longer period of English articles is encrypted, and then the frequency plaintext and ciphertext letters appear in statistics and for comparison, to observe what is the law.
