About code. Mostly on C++
Visual Studio 2017 has had a larger number of updates throughout its lifetime. At the time of writing this article, there have been ten major updates and countless minor ones. You can check the release notes history for details. Part of the changes was in the debugger. In this article, I will mention three features … Read more
The post-Kona mailing list of the new standards papers has been recently published (you can find it here). Going through the titles I could not help smiling because some of them are really funny. So I decided to make a top 10 of the funniest paper titles.
A user-defined conversion function enables an implicit or explicit conversion between types. Such, a function has the following form (no return type and no parameters):
struct foo
{
operator int() const {return 42;}
};
foo f;
int i = f; // implicit conversion
Function-try-block is a mechanism in C++ to establish an exception handler around the body of a function. The following is an example:
int foo()
{
throw std::runtime_error("oops...");
}
int main()
try
{
foo();
return 0;
}
catch (...)
{
return -1;
}
The Ranges library proposal has been accepted for C++20 at the San Diego meeting of the standard committee in November last year. The library provides components for handling ranges of values aimed at simplifying our code. Unfortunately, the Ranges library is not very well documented, which makes it harder to grasp for those that want to learn it. This post is intended as an introduction based on examples of code written with and without Ranges.
std::equal_range is a general purpose standard algorithm used to find a sub-range of values in a given sorted or at least partitioned range. In this post, I will explain how the algorithm works.
The C++ community has worked hard in the past decade and more to move the language forward, to enrich but also simplify it, and to adopt new paradigms and coding styles. Yet, a single topic, a simple matter of style is splitting the community, in a pure Swiftian manner: the use of the const qualifier that some prefer it on the left of what it modifies, as it has been the de facto standard for decades, and which is now called West const, or to the right of that it modifies, that is a style that more and more people are adopting, and which is now called East const. I don’t particularly like this terms, I would rather use left const and right const, but if this is what the community prefers to use let’s call them so for consistency.
I have been working lately on a C++ library for handling monetary values, currencies, rounding and other related features. It is called moneycpp and it’s a C++ 17 header-only, cross-platform library available on GitHub.
The library is intended for being used in a variety of types of application including ERP systems, banking, finance, insurance, games, and others.
The following is a list of its core requirements:
