The C++23 standard provides several new range adaptors in the ranges library. These include join_with, zip, and zip_transform. In this post, I will briefly show how these should work.

Highlights from Microsoft Build 2020
Posted on
The Microsoft Build 2020 event happened this week, and, unlike all previous editions, it was a digital event only. Moreover, it was also free, so everybody could attend the 48 hours marathon. Microsoft made a lot of announcements and released various products and services for Windows, Azure, Office, Visual Studio, Edge, and more.

C++20 designated initializers
Posted on
The C++20 standard provides new ways to initialize aggregates. These are:
- list initialization with designated initializers, that has the following forms:
T object = { .designator = arg1 , .designator { arg2 } ... }; T object { .designator = arg1 , .designator { arg2 } ... }; - direct initialization, that has the following form:
T object (arg1, arg2, ...);
In this article, we will see how list initialization with designated initializers work.

Today I wanted to rework an example that I wrote years ago. I was a client-server example using the C++ REST SDK. I haven’t worked with the library for a while, so I needed to install the latest version first. If you go to the C++ REST SDK project page it says you need to…
