vc++,CPoint list operator==

akira32

我定?一??CPoint的list,我?在要判?辔夷壳耙?尤氲狞c,是否重?,我想用find,可是?s出?一些??
我想??一下是否要?承CPoint去改operator==?

std::list<CPoint> m_point_list;
void Func1(CPoint point_cell)
{
std::list <CPoint>::iterator result;
result==std::find(m_point_list.begin(),m_point_list.end(),&point_cell);
}

我怎么觉得你应该写 = 而不是 ==
还有，list<> 有内部的find函数，不用调用公共的find
