ret= std::equal_range(vec_i.begin(),vec_i.end(),1); 2.set_difference 算法set_difference可以用来求两个集合的差集,此处的集合可以为std::set,也可以是std::multiset,但是不可以是hash_set以及hash_multiset。为什么呢?因为set_difference要求两个区间必须是有序的(从小到大排列),std::set和std::multis...
对于类成员函数、lambda表达式或其他可调用对象就无能为力了,因此,C++11推出了std::function与std::...

equal_range函数其实是upper_bound函数+lower_bound函数构成的,它的作用是求一个有序的容器中 与key相等元素的上界与下界 1. equal_range的返回值是两个迭代器 1. 代码例子 multimap< float,Material_New*, std::greater<float> >::iterator it = m_multi_mater_map.begin(); ...
std::pair<const_iterator,const_iterator> equal_range( const K& x ) const; (4) (C++14 起) 返回容器中所有拥有给定关键的元素范围。范围以二个迭代器定义,一个指向首个不小于 key 的元素,另一个指向首个大于 key 的元素。首个迭代器可以换用 lower_bound() 获得,而第二迭代器可换用 upper_bound(...
