+# sub函数说明文档    
+## 一、工程说明  
+- 本工程的配置类型是一个动态库文件，目的是生成一个可被其他工程调用动态库，动态库的函数功能是：输入两个int类型的数，返回两数之差。
+## 二、头文件 sub.h  ，放的是sub函数声明
+```C  
+#ifndef _SUB_H_
+#define _SUB_H_
+#ifdef sub_EXPORTS
+#define sub_EXPORTS _declspec(dllexport)
+#else
+#define sub_EXPORTS _declspec(dllimport)
+#endif
+/*
+**函数名： sub
+**参数：int ，int
+**返回值：int
+**函数功能：传入两个int类型的参数，对其进行减法运算并返回差值。
+*/
+sub_EXPORTS int sub(int x, int y);
+
+#endif
+```
+## 三、源文件 sub.cpp  ，放的是sub函数的另一
+```C
+#include"sub.h"
+int sub(int x, int y)
+{
+	return x - y;
+}
+```
+## 四、单元测试   
+- 手动创建ini文件并添加测试样例，之后在单元测试的源文件里对ini文件进行读取解析 ，完成以后获取单元测试的结果，保证代码覆盖率在80%以上。其中对ini文件的读取另封装了函数，见下面的源码。  
+1. ini文件内容  exl.ini  
+  ```
+    [TestMethod1]   #测试样例1
+    na=10           #函数第一个入数
+    nb=4            #函数第二个入参
+    nExpect=6      #两个入参相减的正确结果
+	[TestMethod2]
+	na=7
+	nb=3
+	nExpect=4
+  ```   
+  2. 读取ini文件的函数   int CalcCount(int n, char(*str)[10])
+```C
+/*
+**函数功能：获取一个ini文件里有多少个节，并通过二维指针数组将节名带出来。
+* 函数名：CalcCount（）
+* 入参：int n              --------节的个数
+*       char (*str)[10]    --------二维数组指针，10是节名的长度，可以根据需求修改
+*返回值：int               --------返回节的个数

+	{
+		if (chSectionNames[0] == '\0')//如果第一个字符就是0，则说明ini中一个节也没有，
+		{
+			break;
+		}
+		if (chSectionNames[i] == '\0')
+		{
+			count++;
+			pSectionName = &chSectionNames[i - j]; //找到一个0，则说明从这个字符往前，减掉j个偏移量，
+												   //就是一个节名的首地址 
+			j = -1;                               //找到一个节名后，j的值要还原，以统计下一个节名地址的偏移量
+												  //赋成-1是因为节名字符串的最后一个字符0是终止符，不能作为节名
+			for (m = 0; m <= strlen(pSectionName); m++)//把找到的节名保存到str中
+			{
+				str[k][m] = *(pSectionName + m);
+			}
+			k++;//变量自加，用来保存下一个节名
+			//在获取节名的时候可以获取该节中键的值，前提是我们知道该节中有哪些键。
+			if (chSectionNames[i + 1] == 0)
+			{
+				break;      //当两个相邻的字符都是0时，则所有的节名都已找到，循环终止
+			}
+		}
+	}
+	return count;//返回节名的个数
+}
