Strongly typed constructors

Published December 5, 2016 - 8 Comments

This is the first post of a series on the topic of expressive types, that is, types that express what they represent, rather than how they are implemented. By carrying meaning, these types improve the readability and safety of the code. Here is the series about strong types: Strongly typed constructors Strong types for strong interfaces Passing […]

Partial queries with optional<T>

Published December 1, 2016 - 5 Comments

Clearer interfaces with optional<T> showed what optional<T> was, and how to make interfaces clearer by using it as a return type. If you’re not familiar with optional, I would recommend you to read it first. Here I present a example of using optional as an argument, to leverage on its “not set” semantic. The need we’ll work […]

Return value optimizations

Published November 28, 2016 - 2 Comments

In Make your functions functional, we saw that it was preferable to have functions return objects by value, for code clarity. Now to avoid incurring performance costs by doing this, the compiler can optimize away the copies related to the return by value, if you respect a few simple rules. This post describes these optimizations and shows […]

Clearer interfaces with optional<T>

Published November 24, 2016 - 0 Comments

The need for representing a value that is “empty”, “null”, or “not set” arises regularly in code but often leads to clumsy or brittle solutions. This need may appear with a function that needs to return a value but may not be able to compute it in all cases. In this case, several solutions are […]

Make your functions functional

Introduction : global variables Global variables are a Bad Thing. Everyone knows this, right ? But do you know exactly why ? I have asked this question around, and many of us can’t exactly explain why global variables should be avoided. It is not a question of scope. Indeed, global constants have the same scope as […]

How I came to create Fluent C++

Published November 15, 2016 - 3 Comments

Getting better by teaching I’ve quite recently come to the realization of the immense value of teaching. Not teaching as in formal education, but rather teaching as in explaining things to people, clearing the confusion around a topic, or simply sharing something I’ve learned. In a nutshell, when you teach, you get better at the topic […]

Becoming Fluent in C++

Published November 4, 2016 - 1 Comment

Hi everyone! I’m Jonathan Boccara, your host on Fluent C++. The purpose of this blog is to study techniques to write expressive code in C++. By expressive code we mean code that expresses the intent of the programmer that wrote it. Code you can read and understand. Code that says what it means to do. […]
