intersting problem with inheritance and iterators

[puzzlecracker]

struct A{
std:string name;

};

struct B:public A{

};
std::vector<A*>vec;
....

std::vector<A*> const_iterator beg=vec.begin(), end=vec.end();

for(;beg!=end;beg++)
std::cout<<beg->name<<std::endl;
ok, std:string name from class A is NOT visible. WHY? what is the
solution

Apart from the other syntactic errors, beg->name means (*beg).name
however (*beg) is of type A* const. Probably you want (*beg)->name.

here is the exact code - what is wrong:
struct A{
std::string name;
};

struct B{
std::vector<A*> dirent;
};
....

void FileSystem::dump(A * e){

if(e==0) return;

vector<A*>::const_iterator
beg=(e->dirent).begin(),end=(e-dirent).end();

That's the exact code? Why do you have "..." in the middle of your
code? Why do you have an unmatched brace '{'? Why is there no
definition of the class FileSystem? What does "e-dirent" mean? And so on.

Don't expect much help until you put in a little more effort towards a
clear and comprehensible question.
