map<const string, CmdExec *>::iterator it;
for( it = _cmdMap.begin() ;it !=_cmdMap.end();it++)
{
it->second->help();
}
cout<<endl;
上面这程式码
会出现错误
no match for ‘operator=’ in ‘it = ((const
CmdParser*)this)->CmdParser::_cmdMap.std::map<_Key, _Tp, _Compare,
_Alloc>::begin [with _Key = const std::basic_string<char,
std::char_traits<char>, std::allocator<char> >, _Tp = CmdExec*, _Compare =

std::allocator<char> > >, _Alloc = std::allocator<std::pair<const

上面这航是啥意思？
