std::list example:: iterate list

Two ways to iterate list

1. use this one when need to remove item from the list.

	std::list<int>::iterator it = m_clientList.begin();

		while (it != m_clientList.end()) {
			if (xxxx) {
				it = m_clientList.erase(it);
			} else {
				++it;
			}
		}

2. normal iterate

list<int> copylist = GetClients();
		for (std::list<int>::iterator it = copylist.begin();
				it != copylist.end(); ++it) {
			int n = *it;
//do something with n 
		}
