英文文本信息熵的计算
说明： 实用C++计算一篇英文文本的信息熵
1、 读取文档，统计英文字母及空格出现的次数；
(将小写字母转为大写字母进行计数)
2、 求概率分布P(X)；
3、 根据定义求信息熵。(Computing the information entropy of an English text with C + +
1. Read the document and count the number of English letters and spaces;
(convert lowercase letters to uppercase letters for counting)
2. Calculate the probability distribution P (x);
3. According to the definition of entropy.)
