游戏开发中，免不了有对char*的操作，以及对List的使用。如果不封装关于此方面的类的话，在使用的时候，将十分的不方便，比如对char*的连接，赋值等等操作。
这里是CEasyStr和CEasyList类的具体代码：
#include "EasyList.h"

mHead->next=mLast;
mLast->pre=mHead;

}
CEasyList::~CEasyList(void)
{
}
int CEasyList::Add(void *p)
{
CEasyNode *bb= new CEasyNode;
bb->data=p;
bb->pre=mLast->pre;
bb->next=mLast;
mLast->pre->next=bb;
mLast->pre=bb;
//mLast->pre->next=bb;
return ++mCount;
}
int CEasyList::Count()
{
return mCount;
}
CEasyNode* CEasyList::GetNode(int index)
{
if(index>=mCount || index<0)
{
return NULL;
}
CEasyNode* pNode;
pNode=mHead;
for(int i=0;i<=index;i++)
{
pNode=pNode->next;
if(pNode==NULL || pNode==mLast)
{
return NULL;
}
}
return pNode;
}
void* CEasyList::Get(int index)
{
CEasyNode *pNode=GetNode(index);
if(pNode)
{
return pNode->data;
else
{
return NULL;
}
}
int CEasyList::Delete(int index)
{
CEasyNode* pNode;
pNode=GetNode(index);

{

}
return mCount;
}
