STL Algorithms in Action -- Haitham Gad

Use of STL Algorithm as building block to implement various high level algorithms.

STL Algorithms in Action

by Haitham Gad

From the article:

We saw variations of three common sorting algorithms implemented generically and compactly using STL algorithms. In general, STL algorithms are more applicable than they look. The key to utilizing them is to always ask whether the raw loop I’m about to write (or the one I’m reading) can be replaced by a packaged STL algorithm. You’d be surprised how many times this question can be answered affirmatively.

Trip Report: C++ Standards Meeting in Jacksonville, February 2016

by Botond Ballo

From the article:

Last week I attended a meeting of the ISO C++ Standards Committee in Jacksonville, Florida. This was the first committee meeting in 2016; you can find my reports on the 2015 meetings here (May 2015, Lenexa) and here (October 2015, Kona). These reports, particularly the Kona one, provide useful context for this post...

Concepts without Concepts--Andrzej KrzemieĊ„ski

Concetps are good, but how can we get them?

Concepts without Concepts

by Andrzej Krzemieński

From the article:

“Concept” can mean two things in the context of C++ generic libraries:

  1. Something informal: something we know about template parameters, and can tell to other human programmers, e.g. in documentation.
  2. A language feature.

This post is about concepts in the first sense. It claims that we had concepts for quite a while already, and shows how we can use them to make generic libraries easier to use...

Guidelines Support Library Review: string_span--Marius Bancila

What is a string_span?

Guidelines Support Library Review: string_span<T>

by Marius Bancila

From the article:

In a previous post I have introduced the span<T> type from the Guidelines Support Library. This is a non-owning range of contiguous memory recommended to be used instead of pointers (and size counter) or standard containers (such as vector or array). span<T> can be used with strings, but the Guidelines Support Library provides a different span implementation for various types of strings. These string span types are available in the string_span.h header.
