+# ##**基于cortex-m3-emulator实现哈希表并测试验证**##
+
+## 1. 简介
+
+基于矽璓模拟器cortex-m3-emulator，实现哈希表,并支持链地址法解决哈希冲突，编写测试程序进行验证
+
+## 2. 数据结构设计说明
+```
+//定义哈希表的节点
+typedef struct HashNode{
+    int val;
+    struct HashNode *next;
+}hash_list;
+
+```
+```
+//定义哈希表的大小
+#define HashTableSize 10
+// 创建哈希表
+ hash_list* hash_table[HashTableSize];
+```
+```
+//函数定义说明
+void InitHash();//创建哈希表
+int ComputeHash(int value);//哈希函数，返回在哈希表中的下标
+void InsertHash(int key, int value);//根据key寻找元素在哈希表中的位置，并且使用链地址法解决哈希冲突
+void DeleteHash(int key);//删除哈希表中某个元素
+int SearchHash(int key);//根据value寻找在哈希表中的位置，返回值为在取模后的第几个
+void PrintHash();//打印哈希表
+void TestHash(int argc, char *argv[]);//测试程序，函数参数为对哈希表的操作以及数字
+```
+## 3. 测试程序说明
+测试程序为TestHash，设置有有参函数，参数设置为字符串数组，可输入包括 insert、delete、search、print和clean命令，并可输入哈希表操作数字，根据输入参数完成哈希表的插入、删除、查找、输出和销毁操作，通过atoi()函数将字符数字转为int类型
+
+
+## 4. 运行结果（##需结合运行测试截图按步骤说明##）
+哈希表插入数字9

+输出哈希表

+销毁哈希表并输出
