The latest C++ standard is now upon us, so it’s time to have a look at some of its new features.

To put one of the new features into context we’re going to have a look at – as the title suggests – multiple function return values

I should really distinguish between the following:

A Subroutine (or Subprogram) is a parameterised block of code that can be called multiple times from within a program.
A Procedure is a subroutine that may have multiple input […]

If you work in high-integrity or safety-critical software then you have a duty-of-care to:

Ensure your code does what it should
Ensure your code doesn’t do what it’s not supposed to.

Moreover, you’re typically required to both demonstrate and document how you’ve achieved this duty-of-care. Typical mechanisms for demonstrating compliance include unit testing and static analysis; documentation usually includes function specifications and test results. The amount of testing, static analysis and documentation you (have to) do depends on the integrity level of your […]

Uniform initialization syntax is one of my favourite features of Modern C++.  I think it’s important, in good quality code, to clearly distinguish between initialization and assignment.

When it comes to user-defined types – structures and classes – brace initialization can throw up a few unexpected issues, and some counter-intuitive results (and errors!).

In this article, I want to have a look at some of the issues with brace initialization of user-defined types – specifically, brace elision and initializer_lists.
