<p><strong>二、正文</strong></p>
<p><strong>1.项目完成情况:</strong></p>
<p><strong>1.1</strong> <strong>基本功能（完成）</strong></p>
<p>wc.exe -c input.c //返回文件 file.c 的字符数</p>
<p>wc.exe -w input.c //返回文件 file.c 的单词总数</p>
<p>wc.exe -l input.c //返回文件 file.c 的总行数</p>
<p><strong>1.2 扩展功能（未完成）</strong></p>
<p>wc.exe -s //递归处理目录下符合条件的文件</p>
<p>wc.exe -a input.c //返回更复杂的数据（代码行 / 空行 / 注释行）</p>
<p>wc.exe -e stopList.txt // 停用词表，统计文件单词总数时，不统计该表中的单词</p>
<p>[file_name]: 文件或目录名，可以处理一般通配符</p>
<p><strong>2.实现代码</strong></p>
<p><strong> 2.1 main函数实现参数传递</strong></p>
<div class="cnblogs_code">
<pre class="blockcode">1 int main(int argc, char* argv[]) {
2 Test(argc, argv);//测试
3 getchar();
4 return 0;
5 }</pre>

<p><strong>2.2 GetOption函数实现参数解析</strong></p>
