c++ - Polymorphism,STL,find and operator== -

i ran problem. have class a,and class inherits a,lets call class b. have virtual functions. want compare , b class c operator==. if want have list of a's,lets in stl list, must use pointer a,so like:

list<*a> list; 

and have: c something

but now,i cant use function:find(list.begin(),list.end(),something) because cant use operator == pointers(*).

i found solution dont think best,so question is-can better?

    iter=list.begin();     for(iter;iter!=list.end();++iter)     {         if((*iter).operator==(something)             return ...     } 

thank you.

you use find_if, lets provide function check equal values.

auto check_something =       [&something](const list<*a>::iterator& iter){return *iter == something; };  find_if(list.begin(),list.end(),check_something)
