An interview that went viral

by Rainer Grimm

From the article:

I gave the interview for the e-finance-blog "efinancialcareers". I essentially stated the following:

• C++ is heavily used in the finance industry, for game developers, and in the automotive industry.
• When you want to learn C++, start at least with C++11.
• C++ is often used to build infrastructure.
• C++ is too big to fall.

... In total, I got almost 2000 comments. Today, I want to present the main points about the final interview, because this is my motivation for writing articles, posts, and books, recording videos, and teaching and mentoring C++...

Using modules in the big three compilers

Using modules in the big three compilers: a small experiment

 From the article:

The goal of my experiment was to see how easy it is to write code that a) uses C++20 modules, b) can be compiled by GCC, Clang and MSVC without using conditional compilation, c) imports something from the standard library, d) exports at least one templated function, e) has a peculiarity that makes the module harder to find (in my case, the module is named b but the file that contains it is named a.cppm).

The experiment sort of succeeded...

A canonical example:

The Strategy Pattern

by Rainer Grimm

From the article:

Purpose: Defines a family of algorithms and encapsulates them in objects

Also known as: Policy

Use case:

• Different variations of an algorithm are needed
• The client does not need to know the algorithm
• The algorithm should be exchangeable at the run time of a program...

With or without actual templates:

The Template Method

by Rainer Grimm

From the article:

The key idea of the Template Method is easy to get. You define the skeleton of an algorithm that consists of a few typical steps. Implementation classes can only override the steps but cannot change the skeleton. The steps are often called hook methods...

Lambdas

Modern C++ In-Depth — Lambdas, Part 1

by Phani Adusumilli

From the article

While lambdas do not allow us to write anything we could not have written before their introduction, they greatly improve the ease with which we can write function objects and callbacks.

C++ constexpr parlor tricks: How can I obtain the length of a string at compile time?

by Raymond Chen

From the article:

Say you want to obtain, at compile time, the length of a compile-time string constant. The problem is that the strlen function is not constexpr...

The Proxy Pattern

by Rainer Grimm

From the article:

A proxy controls access to another object, allowing you to perform additional operations before or after you access the original object. Sound familiar?

Which idiom is characteristic of C++? Right: RAII (Resource Acquisition Is Initialization). RAII is the C++ way to implement the Proxy Pattern. Here are the facts about the Proxy Pattern. ...

Using final in C++ to improve performance -- Niall Cooling

Using final in C++ to improve performance

by Niall Cooling

From the article:

The final specifier was introduced in C++11 to ensure that either a class or a virtual function cannot be further overridden. However, as we shall investigate, this also allows them to perform an optimization known as devirtualization, improving runtime performance.
