Is there a STL utility/algorithm to do delete *the_object_iterator; on all the objects? So that I can clear() safely? The STL container is a set and the objects are pointers to C++ classes created wit
tl;dr: Is it is possible to implement quicksort on a doubly linked list efficiently? My understanding before thinking about it was, no, its not.
I\'m trying to use the C++ Standard Library algorithm unique (with BinaryPredicate). I\'ve created a vector of pairs; each pair is like \"(first=a vector of 4 doubles, second=an integer)\". The seco
The error I get says that the fill_n line below is trying to use the deleted copy constructor: why is it not trying to use the move constructor?I tried wrapping it in a std::move but that didn\'t help
I have an array of structs; the array is of size N. I want to remove duplicates from the array; that is, do an in-place change, converting the array to have a single appearance of each struct. Additi
Hi was I hoping someone would help understand this behaviour of the below code. #include <iostream>
I have a class representing a user ca开发者_高级运维lled Nick and I want to use std::find_if on it, where I want to find if the userlist vector has an object included with the same username I pass in.
The STL algorithms are a pretty useful thing in C++. But one thing that kind of irks me is that they seem to lack composability.
I have a container of std::shared_ptr.I want to compare two containers using std::equal.The class A has operator== defined.I want equal to compare if each element is equivalent using its operator==, n
I have a set of shared_ptr, and I\'d like to use remove_copy_if with a custom function object for the predicate.I didn\'t know the \"best\" way to do it.Right now, I\'ve got this working:
