STL 常用算法：sort,unique,

1.删除一个vector中的重复元素：

struct ST_MY

{

    int m_nID;

    int m_nType;

 

    bool operator < ( const ST_MY& oMY ) const

    {

        return m_nID < oMy.m_nID;

    }

}

 

class CCompEqual

{

    bool operator() ( ST_MY& oMY1, ST_MY& oMY2 )

    {

        return oMY1.m_nID == oMY2.m_nID;

    }

}

 

#include

vector< ST_MY > vctOp;

sort( vctOp.begin(), vctOp.end() );

vector< ST_MY >::iterator it = unique( vctOp.begin(), vctOp.end(), CCompEqual() );

vctOp.erase( it, vctOp.end() );
