STL中vector元素的一些操作方法

1.定义结构体类型的vector

typedef struct _LABEL_VECTOR_{DWORD m_id;CString m_sender;CString m_receiver;CString m_content;unsigned int m_len;CString m_time;}LABLE_VECTOR;typedef vector<LABLE_VECTOR> VECTOR_LABLE;

2.存储此种类型的数据

<pre name="code" class="cpp">xLableStruct.m_id = it->at(0);xLableStruct.m_sender= it->at(1);xLableStruct.m_receiver=it->at(2);xLableStruct.m_content= it->at(3);xLableStruct.m_len= it->at(4);xLableStruct.m_time= it->at(5);m_xVectorLable.push_back(xLableStruct);

3.取出第n个元素中的m_time值

VECTOR_LABLE::iterator it;it = m_xVectorLable.begin();it += n;

CStsing tim = it->m_time;
