我的代码为什么会出错？

[AppleII]

class CXmlArray  
{
public:
	CXmlArray();
	virtual ~CXmlArray();
	
	CXmlArray& operator = (const CXmlArray& obj)
	{
		if(this != &obj)
		{
			m_name = obj.m_name;
			m_value = obj.m_value;

			// m_subarray要进行深拷贝
			map<string, CXmlArray*>::iterator Iter;
			for(Iter = obj.m_subarray.begin(); Iter != obj.m_subarray.end(); Iter++)
			{
				CXmlArray *pxmlArray = Iter->second;
				CXmlArray *pnewArray = new CXmlArray();
				m_subarray.insert(Iter->first, pnewArray);
			}
		}
		
		return *this;
	}
	
	CXmlArray operator[](const char *szName)
	{
		return *m_subarray[szName];
	}
private:
	map<string, CXmlArray*> m_subarray;
	string m_name;
	string m_value;
};

编译无法通过啊，说Iter = obj.m_subarray.begin(); 无法赋值

[疯癫小程序]

map<string, CXmlArray*>::iterator Iter;
for(Iter = obj.m_subarray.begin(); Iter != obj.m_subarray.end(); Iter++)
{
CXmlArray *pxmlArray = Iter->second;
CXmlArray *pnewArray = new CXmlArray();
m_subarray.insert(Iter->first, pnewArray);
}
========================
你的Iter和obj.m_subarray.begin()显然不是同一种变量，而且还不能兼容，当然就赋值不了了。

map<string, CXmlArray*>::const_iterator Iter；
m_subarray.insert(make_pair(Iter->first,pnewArray));

这样修改看下

// m_subarray要进行深拷贝
			map<string, CXmlArray*>::const_iterator Iter = obj.m_subarray.begin();
			for(; Iter != obj.m_subarray.end(); Iter++)
			{
				//CXmlArray *pxmlArray = Iter->second;
				CXmlArray *pnewArray = new CXmlArray();
				m_subarray.insert(make_pair<string, CXmlArray*>(Iter->first, pnewArray));
			}
