stl中vecter和pair组合达到字典的效果

	typedef  std::pair<string, int>  beanUnit;
	std::vector<beanUnit> vec;
	vec.push_back(beanUnit("xuhaitao",36));
	vec.push_back(beanUnit("wangerxiao",63));
	vec.push_back(beanUnit("jidan", 25));
	vec.push_back(beanUnit("mao", 5));

	std::vector<beanUnit>::iterator i = vec.begin();
	std::vector<beanUnit>::iterator end = vec.end();



	while (i != end) {
		cout << i->first <<i->second << endl;
		++i;
	}
