Map封装，方便以后直接调用

MyMap.h

<pre name="code" class="cpp">//#ifdef MYMAP_H//#define MYMAP_H#include <map>#include <string>#include <stdio.h>using namespace std;class MyMapClass{public://构造函数MyMapClass();//析构函数~MyMapClass();//设置数据bool SetMapData(string key, int value);bool SetMapData(int key,string value);//获取数据int GetMapDate(string key);string GetMapDate(int key);//删除数据bool DeleteMapDate(string key);bool DeleteMapDate(int key);void PrintMap();//打印Map信息private:map<string,int> MapString;  //[string] = intmap<int,string>MapInt;int MapStringMaxSize;//限制string型容量大小    int MapIntMaxSize; //限制int型容量大小};//#endif
