WebThis can either be a function pointer or a function object. Return value A pair object, whose member pair::first is an iterator to the lower bound of the subrange of equivalent values, and pair::second its upper bound. The values are the same as those that would be returned by functions lower_bound and upper_bound respectively. Example WebThe upper_bound() algorithm finds the last position in a sequence that value can occupy without violating the sequence's ordering. upper_bound() 's return value is the iterator …
Webstd::map:: lower_bound. 1,2) Returns an iterator pointing to the first element that is not less than (i.e. greater or equal to) key. 3,4) Returns an iterator pointing to the first element that compares not less (i.e. greater or equal) to the value x. This overload participates in overload resolution only if the ... WebThe std::upper_bound () can be used for a variety of data structures. The std::upper_bound () is a method in the Standard Template Library ( STL) in C++. It returns an iterator pointing to the next grater value in the range [first, last). If no such element is found it returns the pointer pointing to the last.

WebMay 17, 2011 · From the standard, 25.3.3.1/3, on std::lower_bound (): Returns: The furthermost iterator i in the range [first, last] such that for any iterator j in the range [first, i) the following corresponding conditions hold: *j < value or comp (*j, value) != false. From that, you may use bool comp (foo a, int b)
