**1 需求分析**  
 **1) 问题描述：** 读入一个（最多9个）C程序代码文件，统计程序中代码、注释和空行数以及函数的个数，显示函数名并生成相应的记录日志。  
 **2) 基本要求如下：**   
（1）、把程序文件（如.c或者.txt等）按字符顺序读入源程序；  
（2）、输入正确性检查；  
（3）、边读入程序，边识别统计代码行、注释行和空行，同时还要识别函数，统计代码个数；  
（4）、最多允许一次分析9个文件  
  
  
**2 显示结果**  
备注：本文的代码试验IDE为VS2013。本代码对比较常规的编程习惯下编写的C代码可以比较好的识别，但是对一些特殊情况不能识别。

**1)输入正确的文件个数和路径**

**2）输入正确时生成的日志文件**

**3 程序结构**

**1）整体结构**

**2）分析模块结构**

**4 源代码**
