c++ - Iterate through a list of objects and point to the node that matches a certain criteria -

i using custom data structure 'block' , have stored several blocks in list:

 list openlist<block> 

i need iterate through each block, access data member 'f' (an integer) , check has lowest f cost.

my logic have pointer pointing best block value, rather each time copying best blocks values.

here's code:

for (std::list<block>::iterator openi = openlist.begin(); openi != openlist.end();  openi++){         if ((*openi).f < bestfcost){             bestfcost = (*openi).f;             // here's need help....         }     } 

i don't think i'm asking of iterator possible. wish set

 block * q  

to data iterator points to, need entire object not data members.

edit: simple solution! initilised q typo (q* instead of *q)!

block * q = 0;

then in part of loop commented:

 q = &(*openi) 

:)

*openi of type block, right? can take address of that:

block * q = &*openi; 

the &* might seem redundant, * operator on iterator, returning block type, opposed scenario's * dereference, , & references again.

or can store iterator itself:

std::list<block>::iterator q = openi; 

or can store object value, assuming implemented copy constructor:

block q = *openi;
