I have a deque object.
Can I insert pointers into the queue? (I heard I cannot
insert pointer into a queue)
like this:
===============
std::deque < Sock* > * socks;
socks = new deque< Sock* >;
Why use new here?
int port = 4322;
for ( int i = 0; i< 10; i++ ) {
Sock * sock = new Sock();
sock->Create1(this, port);
socks->push_back(sock);
}
later I will loop the queue of socket:
===============
for ( std::deque<Sock>::const_iterator iter = socks->begin(); iter !=
socks->end(); iter++ ) {
for ( std::deque<Sock*>::const_iterator iter = socks->begin();
iter != socks->end(); ++iter ) {
Sock temp = iter->first; // get the 1st socket
A deque iterator does not have a member first.
Unless you want to copy the object, you would require:
const Sock& temp = **iter;
Note the use of const reference. *iter is a Sock*.
