作业要求
实现一个命令行文本计数统计程序。能正确统计导入的纯英文txt文本中的字符数，单词数，句子数。
具体命令行界面要求举例：命令模式： wc.exe [参数] [文件名]
wc.exe -c file.txt 统计字符数
wc.exe -w file.txt 统计单词数
扩展功能（加分项）：统计代码行、空行、注释行等，并提供相应命令接口。
作业要求：
项目代码上传到自己的码云(需自行注册)。
程序和参数名可以按个人喜好命名。项目文档应包含项目说明，写入README.MD。该说明应该包含:
a. 项目的简介及其相关的用法;
b. 文件列表及其相关说明;
c. 例程运行及其相关结果。
码云上传的项目要求必须通过多次提交(commit)体现各个版本更迭和运行结果截图。
版本号分别为
v0.1 空项目；
v0.2 项目完成基础功能
v0.3 项目完成扩展功能（加分项）
编写对应的单元测试。
a. 实现基本功能的测试；
b. 单元测试包含更多的测试用例。（加分项）
使用选用的IDE附带的工具进行performance test。（加分项）
交作业时需直接附上自己的码云仓库地址。

his story is called "The Farmer and the Snake." Every day,
a farmer went to the city to sell his flowers and farm produce
and then went home after selling all his things. One day, he
left home very early, so early that when he arrived at the
city, the gate was still closed. So he lay down to take a
nap, when he awoke he found that the storage bin containing
his farm produce had become empty except that there was a
gold coin inside. Although all the things in the bin had
vanished, the gold was much more valuable so he was still
very happy. He thought most probably someone had taken
his things and left the payment there, and went home
happily with the money.
The next day, the farmer again went out to sell his things
but again arrived too early so he slept outside the city
gate just like he had done the day before. And the incident
repeated itself. All the produce that the farmer had brought
disappeared, and there was a gold coin in the bin! At that
time, gold was very valuable. One gold coin had a value many
times higher than the farmer's produce.
Then one day some time later, the farmer's father asked him,
"Where have you gotten so many gold coins lately? Where did
the money come from?" So the farmer revealed to his father
what had happened. After listening to his story, the father
thought, "One day I'll follow my son as he goes out, and
see who's been consuming his things and leaving the money
in the bin."
So one day, when the farmer went out to do business, his father
quietly followed him. While the farmer was sleeping near the
city gate, his father saw a snake crawl up to his bin and
eat his produce. Having finished eating, the snake once again
spat a gold coin into the bin as payment to the farmer before
leaving. Seeing this, the farmer's father thought, "If I kill
the snake, I'll be able to seize all its gold coins!" He then
picked up a stone and cut the snake into two parts.
At that time, the head and trunk of the snake were already in
its den, and only the tail was outside. The father thought that
there must be a big treasure in the den so he told his son to
reach inside for it. But unexpectedly, when the farmer reached
his hand into the den, the snake bit and killed him! Even though
it had been cut into two, the snake could still bite! I understand
how this could have happened because that was how I got bitten
when I was small. At that time, I saw a centipede that had been
beaten and squashed by someone, leaving only the head intact. I
thought it was dead, and to make sure, I poked it with my foot.
It bit me hard and I cried for three days. (Laughter) I was really
dumb! Remember! Don't play with a centipede even if it looks dead.
Sometimes it just fakes death; it's not really dead.
